THK GSR35TSS Linear Guide Block LM Guide

THK GSR35TSS Linear Guide Block LM Guide

THK GSR35TSS is a linear guide block from the THK GSR LM Guide series, using recirculating balls to provide controlled linear motion along a compatible profiled guide rail. The model belongs to nominal size GSR35 and forms the moving component of a complete linear guide system. For replacement purposes, the full GSR35TSS designation should be verified rather than selecting a block solely by nominal size 35.

What Is THK GSR35TSS?

THK GSR35TSS is the moving block of a:

THK LM Guide

linear motion system.

The block travels along a profiled guide rail while balls circulate continuously through internal return paths.

This creates rolling contact between the guide block and rail and enables controlled linear movement along the guide axis.

Technically, LM Guide block or linear guide block is a more precise description of GSR35TSS than the generic term “linear bearing.”

THK GSR Series

GSR35TSS belongs to the:

THK GSR Series

The GSR family is part of the THK LM Guide product system.

A profiled linear guide arrangement consists principally of:

LM Guide block

and:

LM Guide rail

The GSR35TSS is the moving block and must operate with a compatible rail from the appropriate THK GSR system.

GSR35 Nominal Size

Within the designation:

GSR35TSS

the section:

GSR35

identifies the product family and nominal size.

The number:

35

is an important identification parameter, but it does not mean that every THK size 35 linear guide component is interchangeable.

Different THK series can have different:

rail profiles

block geometry

mounting dimensions

ball circulation systems

load characteristics

sealing arrangements

The complete designation GSR35TSS should therefore be retained during product identification.

Recirculating Ball Construction

THK GSR35TSS uses a:

recirculating ball system

As the guide block moves along the rail, the balls roll through the loaded raceway section and then circulate through internal return passages inside the block.

They subsequently return to the loaded zone, creating a continuous circulation path.

This recirculating principle is fundamental to the operation of THK LM Guide systems.

How Does THK GSR35TSS Work?

During linear movement:

balls roll between the block and rail raceways

then:

pass through the internal return system

and:

re-enter the loaded raceway section

This creates a continuous ball circulation circuit.

The block can therefore travel along the compatible profiled rail while the rolling elements circulate internally.

GSR35TSS Block and Guide Rail

The designation:

GSR35TSS

identifies the guide block.

A complete linear guide arrangement also requires a compatible:

THK GSR guide rail

The rail defines the linear travel path, while GSR35TSS moves along that rail.

When ordering, it is therefore important to determine whether the supplied product consists of:

the GSR35TSS block only

or:

a block and rail assembly

The designation GSR35TSS alone should not be interpreted as specifying a particular rail length.

Is THK GSR35TSS a Linear Bearing?

The term:

linear bearing

is commonly used commercially for many different types of linear motion components.

For THK GSR35TSS, the technically more precise terms are:

linear guide block

or:

LM Guide block

GSR35TSS is not a conventional linear ball bushing such as an LM-type cylindrical bushing operating on a round shaft.

Instead, it operates on a:

profiled LM Guide rail

Linear Motion Principle

The purpose of the GSR35TSS block is to provide guided movement along a defined linear path.

Rather than relying on direct sliding contact, the system uses rolling balls between the block and guide rail.

The profiled rail establishes the travel path, while the internal recirculation system allows the rolling elements to circulate continuously as the block moves.

THK GSR35TSS in Industrial Linear Motion Systems

GSR35TSS is a component for:

industrial linear motion systems

The exact machine application should be determined from the original equipment documentation or from the technical requirements of the linear guide arrangement.

The product should not be assigned to a specific machine type solely on the basis of its GSR35TSS designation.

For replacement applications, the existing rail and block configuration should be identified before ordering.

GSR35TSS vs Conventional Linear Ball Bushing

A conventional linear ball bushing typically operates on a:

round shaft

THK GSR35TSS operates as part of a:

profiled rail guide system

These are different linear motion concepts.

Although both use rolling elements to support linear movement, their:

mounting systems

guide geometry

load paths

and:

interchangeability requirements

are different.

This distinction is important when searching for a replacement.

Can GSR35TSS Be Used with Any THK Size 35 Rail?

No such compatibility should be assumed.

The nominal size:

35

does not establish universal interchangeability between different THK LM Guide series.

Different product families can use different:

raceway geometry

rail profiles

block dimensions

mounting arrangements

and:

internal construction

The correct rail should therefore be selected according to the technical documentation for the:

THK GSR Series

GSR35TSS vs HSR35

THK:

GSR35

and:

HSR35

belong to different LM Guide families.

The common size designation:

35

does not prove compatibility between the two systems.

A GSR35TSS block should therefore not be assumed to fit an HSR35 rail.

Rail profile, block geometry, mounting dimensions and complete technical compatibility must be verified before considering substitution between different THK series.

Rail Length and GSR35TSS

Rail length is:

not defined by the GSR35TSS block designation

The required rail length depends on the specific linear guide configuration and machine design.

Therefore, a listing for:

THK GSR35TSS

should clearly distinguish the guide block from any accompanying rail.

If a rail is included in a particular commercial offer, its length should be specified separately.

Selecting THK GSR35TSS

Before ordering, verify:

Manufacturer - THK

Complete designation - GSR35TSS

Series - GSR

Nominal size - 35

Block configuration

Compatible guide rail

Mounting requirements

Required load conditions

Accuracy requirements

Preload requirements

Environmental conditions

For replacement applications, the safest approach is to identify the complete designation directly from the existing block or machine documentation.

Selecting a Replacement for GSR35TSS

A replacement should not be selected solely from:

THK brand

or:

size 35

The complete linear guide system must be considered.

Important parameters include:

guide series

rail profile

block geometry

mounting dimensions

sealing arrangement

load ratings

accuracy class

preload

Unless these parameters have been verified, another size 35 linear guide block should not be presented as a direct replacement for GSR35TSS.

FAQ - THK GSR35TSS

What is THK GSR35TSS?

THK GSR35TSS is a linear guide block from the GSR LM Guide series that uses recirculating balls to provide linear motion along a compatible profiled guide rail.

Is GSR35TSS a linear bearing?

It may be described commercially as a linear bearing, but the more technically precise term is linear guide block or LM Guide block.

Which THK series does GSR35TSS belong to?

GSR35TSS belongs to the THK GSR series.

What does 35 mean in GSR35TSS?

The number 35 identifies the nominal size of the GSR linear guide system.

Does GSR35TSS include a guide rail?

The designation GSR35TSS identifies the guide block. Whether a rail is included depends on the specific commercial offer and should be verified separately.

Is rail length part of the GSR35TSS designation?

No. Rail length is a separate configuration parameter of the complete linear guide system.

Can GSR35TSS be installed on an HSR35 rail?

Compatibility should not be assumed. GSR and HSR are different THK LM Guide series, even though both may use nominal size 35.

How should a replacement for THK GSR35TSS be selected?

Verify the complete designation, guide series, rail profile, mounting geometry and required technical parameters. Nominal size 35 alone is not sufficient to confirm interchangeability.

AI Overview

THK GSR35TSS is a linear guide block from the THK GSR LM Guide series, nominal size 35. It uses recirculating balls to provide linear motion along a compatible profiled guide rail. GSR35TSS identifies the moving block; rail length is a separate parameter, and compatibility with other THK size 35 series should not be assumed.
