6207-2RS-C4 TIMKEN 35x72x17 mm Deep Groove Ball Bearing

6207-2RS-C4 TIMKEN 35x72x17 mm Deep Groove Ball Bearing

6207-2RS-C4 TIMKEN 35x72x17 mm is a single-row deep groove ball bearing with contact seals on both sides and increased C4 internal clearance. It has a 35 mm bore diameter, 72 mm outside diameter and 17 mm width. The 2RS design helps protect the bearing interior from contaminants, while C4 provides greater internal clearance than Normal and C3 clearance classes.

Technical data - TIMKEN 6207-2RS-C4

The dimensions, sealing arrangement, load ratings and limiting speed correspond to TIMKEN technical data for 6207-2RS-C4.

What does 6207-2RS-C4 mean?

The complete designation identifies both the basic bearing series and important construction features:

• 6207 - deep groove ball bearing from the 62 series
• 2RS - contact seals on both sides
• C4 - increased internal clearance
• TIMKEN - manufacturer

These elements are important when selecting a replacement.

A standard 6207 bearing should not automatically be considered equivalent to 6207-2RS-C4.

Dimensions of 6207-2RS-C4

The principal dimensions are:

35x72x17 mm

where:

• d = 35 mm - bore diameter
• D = 72 mm - outside diameter
• B = 17 mm - bearing width

When selecting a replacement, the sealing arrangement and internal clearance class must be checked in addition to the principal dimensions.

Deep Groove Ball Bearing construction

TIMKEN classifies 6207-2RS-C4 as a standard deep groove ball bearing, commonly abbreviated as DGBB.

Deep raceway grooves allow this bearing type to accommodate primarily radial loads together with certain axial loads in both directions.

Deep groove ball bearings are widely used because of their:

• compact construction
• relatively low friction
• suitability for relatively high rotational speeds
• radial load capability
• ability to accommodate certain axial loads
• broad range of industrial applications

What does 2RS mean?

The 2RS suffix identifies seals on both sides of the bearing.

TIMKEN specifies contact seals for this bearing execution.

The seals help:

• reduce ingress of dust and contaminants
• retain lubricant inside the bearing
• protect the rolling elements and raceways
• support reliable operation in contaminated environments

Compared with an open bearing, contact seals provide additional protection but also generate more friction and can influence permissible operating speed.

What does C4 mean?

C4 identifies an increased radial internal clearance class.

In simplified order:

Normal < C3 < C4

This means C4 provides greater internal clearance than Normal clearance and C3.

C4 should not be interpreted as a higher "quality grade". It is a specific internal clearance class intended for bearing arrangements requiring greater initial clearance.

When is C4 internal clearance used?

Increased internal clearance may be required when operating or mounting conditions reduce the effective bearing clearance.

Relevant factors can include:

• tight interference fits
• temperature differences between bearing rings
• elevated inner-ring temperature
• thermal expansion
• operating speed
• specific machine design requirements
• particular mounting conditions

The correct internal clearance should be selected according to the bearing arrangement and machine manufacturer's requirements.

A C4 bearing should not automatically be replaced with a C3 or Normal-clearance bearing.

6207-2RS-C4 vs 6207-2RS-C3

Both versions can have the same principal dimensions:

35x72x17 mm

and both can use seals on both sides.

The important difference is internal clearance:

• 6207-2RS - standard version without an increased-clearance suffix
• 6207-2RS-C3 - increased C3 internal clearance
• 6207-2RS-C4 - greater C4 internal clearance

C3 and C4 should not automatically be considered interchangeable.

The correct clearance depends on fits, temperatures, speed, load and the requirements of the specific machine.

6207-2RS-C4 vs 6207-ZZ-C4

2RS and ZZ versions can have identical principal dimensions but differ in their closure design.

2RS

Uses seals on both sides. For this TIMKEN execution, these are contact seals providing effective protection of the bearing interior.

ZZ

Uses metal shields. Shields and contact seals have different friction and contamination-protection characteristics.

For this reason, 2RS and ZZ versions should not be selected solely on the basis of identical dimensions.

Load ratings of TIMKEN 6207-2RS-C4

TIMKEN specifies:

Dynamic radial load rating C1: 25.7 kN

Static radial load rating C0: 15.3 kN

These are engineering ratings used in bearing calculations.

They should not be interpreted as direct maximum permissible operating loads for every machine.

Correct bearing selection should consider:

• radial load
• axial load
• load direction
• operating speed
• required bearing life
• internal clearance
• shaft and housing fits
• lubrication
• operating temperature
• contamination
• mounting conditions

Speed of TIMKEN 6207-2RS-C4

TIMKEN specifies a grease limiting speed of:

6300 rpm

This value should not automatically be treated as the permissible continuous operating speed in every application.

Actual operating speed capability depends on factors including load, temperature, lubrication, fits, seal friction and heat dissipation.

C4 clearance and operating temperature

The internal clearance present before installation is not necessarily the same as the clearance remaining during operation.

Interference fits can expand the inner ring or compress the outer ring, reducing internal clearance.

Temperature differences between the inner and outer rings can further change operating clearance.

This is one reason increased-clearance classes such as C3 and C4 are specified for particular bearing arrangements.

C4 should therefore be selected as an engineering requirement rather than simply as an alternative to standard clearance.

How to select a replacement for 6207-2RS-C4

Before selecting an equivalent bearing, verify:

• 35 mm bore diameter
• 72 mm outside diameter
• 17 mm width
• single-row deep groove ball bearing construction
• seals on both sides
• seal type
• C4 internal clearance
• dynamic load rating
• static load rating
• required operating speed
• shaft fit
• housing fit
• operating temperature
• lubrication conditions
• machine manufacturer's requirements

Particular attention should be paid to C4 internal clearance.

A 6207-2RS bearing with identical dimensions but a different internal clearance class should not automatically be considered a functionally equivalent replacement.

Typical applications of 6207 bearings

Deep groove ball bearings from the 6207 dimensional series are widely used in industrial machinery and equipment.

Typical application areas for this bearing category include:

• electric motors
• industrial fans
• pumps
• gearboxes
• industrial machinery
• conveyors
• production equipment
• agricultural machinery
• drive systems
• material handling equipment
• maintenance operations
• industrial service

The suitability of the specific C4 execution must be determined from the operating requirements of the bearing arrangement.

These are typical applications of deep groove ball bearings as a product category and do not confirm that TIMKEN 6207-2RS-C4 is specified for a particular machine or OEM application.

Installation of TIMKEN 6207-2RS-C4

Before installation, inspect the shaft, housing and mounting surfaces and maintain a high level of cleanliness.

Good installation practice includes:

• using appropriate mounting tools
• avoiding direct hammer blows on the bearing
• avoiding transmission of mounting forces through the balls
• checking shaft and housing fits
• protecting the seals from damage
• preventing contamination during installation
• verifying the required operating clearance

When a bearing ring is installed with an interference fit, the mounting force should be applied to the ring being fitted.

Correct mounting is especially important with C4 bearings because fits and operating temperatures influence the final internal clearance.
