MTM 6006 2RS 30x55x13 - Sealed Deep Groove Ball Bearing

MTM 6006 2RS 30x55x13 - Sealed Deep Groove Ball Bearing

MTM 6006 2RS is a single-row deep groove ball bearing with dimensions 30x55x13 mm, equipped with seals on both sides. The 2RS design helps retain lubricant inside the bearing while limiting the ingress of dust, moisture and other contaminants. The deep groove raceway geometry enables the bearing to accommodate primarily radial loads together with axial loads in both directions, making it suitable for electric motors, pumps, gearboxes, drive systems and general industrial machinery.

Dimensions 30x55x13 mm

The principal boundary dimensions of 6006 2RS are:

d: 30 mm
D: 55 mm
B: 13 mm

The designation 6006 identifies the standardized dimensional series with a 30 mm bore, 55 mm outside diameter and 13 mm width.

When selecting a replacement, the sealing arrangement, internal clearance and any additional suffixes should also be checked.

What Does 2RS Mean?

The suffix 2RS indicates that the bearing is equipped with seals on both sides.

The seals perform two important functions: they help retain grease within the bearing and provide protection against external contamination.

This makes the sealed 6006 2RS particularly useful in bearing positions where an open bearing would require additional external protection.

Deep Groove Ball Bearing Design

MTM 6006 2RS uses a single row of balls operating between deep raceway grooves in the inner and outer rings.

Deep groove ball bearings are widely used because they combine:

• low friction
• radial load capability
• axial load capability in both directions
• compact dimensions
• relatively high rotational speed capability
• simple installation

This combination makes the 6006 series suitable for a broad range of rotating machinery.

Radial and Axial Load Capability

The primary function of 6006 2RS is to accommodate radial loads.

Due to the geometry of the deep raceways, the bearing can also support axial forces acting in either direction within the limits of the bearing design.

This distinguishes deep groove ball bearings from many roller bearing designs intended primarily for radial loading.

Grease-Filled Sealed Construction

The 2RS version is supplied as a sealed, grease-lubricated bearing.

The seals help retain lubricant around the rolling elements and raceways. Under typical operating conditions, this type of bearing is used without periodic relubrication.

Actual grease service life depends on operating temperature, rotational speed, load and environmental conditions.

6006 2RS vs 6006 ZZ

Both versions share the same basic 30x55x13 mm dimensions but use different closure systems.

6006 2RS: seals on both sides
6006 ZZ: metal shields on both sides

A 2RS design is generally selected where contamination protection and grease retention are priorities. A shielded ZZ version generally produces less seal friction but provides a different level of protection.

The required version should therefore be selected according to the operating environment.

Typical Applications

MTM 6006 2RS can be used in appropriately designed:

• electric motors
• pumps
• industrial gearboxes
• fans and blowers
• conveyors
• agricultural machinery
• workshop equipment
• production machinery
• mechanical drive systems
• general industrial equipment

Final selection should consider load, speed, operating temperature, internal clearance and environmental conditions.

Replacement Identification - MTM 6006 2RS

When identifying a replacement, verify:

Brand: MTM
Designation: 6006 2RS
Bearing type: Deep groove ball bearing
Dimensions: 30x55x13 mm
Bore d: 30 mm
Outside diameter D: 55 mm
Width B: 13 mm
Closure: Sealed on both sides
Bore type: Cylindrical

Equivalent seal suffixes can vary between bearing manufacturers, so the technical execution should be verified rather than relying solely on the suffix wording.

Operational Advantages

Compact dimensions: 30x55x13 mm geometry provides a small radial installation envelope.

Sealed construction: protection on both sides limits contamination of the rolling contact.

Grease retention: seals help retain the lubricant inside the bearing.

Combined load capability: supports radial loads and moderate axial loads in both directions.

Low maintenance: sealed construction is suitable for bearing positions where regular relubrication is impractical.

Versatile installation: standardized 6006 dimensions allow use in numerous industrial machine designs.

FAQ - MTM 6006 2RS
