EWELLIX LBBR 40-2LS Dimensions

The principal dimensions are:

d: 40 mm - nominal shaft diameter

D: 52 mm - bearing outside diameter

L: 60 mm - overall bearing length

Complete size:

40x52x60 mm

The LBBR 40-2LS is therefore designed for use with a suitable linear shaft having a nominal diameter of 40 mm.

When identifying a replacement, the shaft diameter alone is insufficient. The outside diameter, length, dimensional series, sealing arrangement and bearing construction should also be verified.

What Does LBBR 40-2LS Mean?

The complete designation:

LBBR 40-2LS

identifies a specific EWELLIX linear ball bearing variant.

LBBR - compact linear ball bearing series

40 - nominal 40 mm shaft diameter

2LS - sealed version with seals on both sides

The complete LBBR 40-2LS designation should be retained during product identification and replacement selection.

The suffix is particularly important because it distinguishes the sealed version from other configurations within the product family.

LBBR Linear Ball Bearing Design

The EWELLIX LBBR series uses recirculating balls to provide linear motion along a shaft.

The construction incorporates a polymer cage and steel raceway segments. The rolling elements circulate through the bearing as it moves along the shaft.

This recirculating ball arrangement allows continuous linear travel while maintaining rolling contact between the bearing and the shaft.

Unlike a conventional radial ball bearing, the primary function of the LBBR 40-2LS is not rotational shaft support. It is designed primarily for linear guidance and linear motion.

2LS Sealing

The suffix:

2LS

identifies the version with seals on both sides.

The sealing arrangement helps protect the internal rolling elements and raceway areas against external contamination while supporting lubricant retention within the bearing.

This is an important identification feature of the exact:

EWELLIX LBBR 40-2LS

The 2LS suffix should therefore remain an integral part of the complete product designation.

Factory Lubrication

The EWELLIX LBBR 40-2LS is supplied as a factory-lubricated linear ball bearing.

Product information for this version specifies LGEP2 grease.

Factory lubrication prepares the bearing for installation according to the manufacturer's product configuration. Actual relubrication requirements depend on operating conditions, travel distance, contamination, load and the maintenance strategy of the linear guidance system.

Load Ratings of EWELLIX LBBR 40-2LS

For the exact LBBR 40-2LS, the specified basic load ratings are:

Basic dynamic load rating C: 5500 N

Basic static load rating C0: 4500 N

These values are important when evaluating the linear bearing for a particular guidance system.

However, a linear bearing should not be selected solely according to its nominal load rating. Actual system design can also depend on load direction, shaft support, bearing arrangement, installation accuracy, travel speed, lubrication and environmental conditions.

LBBR 40-2LS - Compact ISO 1 Series

The LBBR product family belongs to the Compact ISO 1 dimensional series.

For the LBBR 40-2LS:

Nominal shaft diameter: 40 mm

Outside diameter: 52 mm

Length: 60 mm

The combination of a 40 mm shaft diameter and 52 mm outside diameter provides a compact radial installation envelope for linear guidance applications.

When replacing an existing bearing, the complete LBBR 40-2LS designation is a better identification basis than shaft diameter alone.

LBBR 40-2LS vs Other 40x52x60 Linear Bearings

Other linear ball bearings may share the same nominal dimensions of:

40x52x60 mm

However, matching dimensions alone do not establish full technical equivalence.

Products can differ in:

internal raceway construction

ball recirculation design

cage construction

sealing arrangement

load ratings

lubrication

shaft requirements

housing requirements

dimensional tolerances

For precise product identification, retain:

EWELLIX + LBBR 40-2LS + 40x52x60 mm

Selection and Interchangeability

When selecting a replacement for EWELLIX LBBR 40-2LS, verify at least:

• Nominal shaft diameter d: 40 mm
• Outside diameter D: 52 mm
• Length L: 60 mm
• linear ball bearing construction
• closed design
• dimensional series
• 2LS sealing arrangement
• required dynamic load rating
• required static load rating
• shaft design and specifications
• housing requirements
• lubrication requirements
• operating environment

Matching 40x52x60 mm dimensions alone should not be treated as confirmation of complete interchangeability.

Linear bearings from INA, Bosch Rexroth, NTN, Samick or other manufacturers should not automatically be identified as direct equivalents solely because their nominal dimensions match.
