LR 5202 2RS MGK 15x40x15.9 mm - Double Row Track Roller Bearing

LR 5202 2RS MGK 15x40x15.9 mm - Double Row Track Roller Bearing

LR 5202 2RS MGK 15x40x15.9 mm is a double row track roller bearing with a 15 mm bore diameter, 40 mm outside diameter and 15.9 mm width. The LR series is designed for applications where the outer ring can operate directly against a suitable track, rail or guide surface. The 2RS designation indicates sealing on both sides of the bearing.

Technical data - LR 5202 2RS MGK

Parameters such as dynamic load rating, static load rating, limiting speed, mass, internal clearance, cage material and lubricant should not be assigned solely from the LR 5202 2RS designation. Where these values are required for engineering calculations, they should be confirmed from documentation for the specific MGK version.

What does LR 5202 2RS mean?

The product designation can be divided into its main identification elements:

• LR - bearing series used for track roller applications
• 5202 - bearing size and design designation
• 2RS - seals on both sides
• MGK - product brand
• 15x40x15.9 mm - principal bearing dimensions

The 2RS sealing arrangement helps protect the internal bearing components against contamination and helps retain lubricant within the bearing.

Construction of the LR 5202 2RS

LR 5202 2RS belongs to the group of bearings designed for use as track rollers.

Unlike a conventional bearing whose outer ring is normally supported by a housing, the outer surface of a track roller can operate directly against a:

• guide
• rail
• track
• cam
• running surface

The double row construction incorporates two rows of rolling elements and is intended to support loads in systems designed for this type of bearing.

Where internal geometry, contact angle or other detailed construction features are important for engineering calculations, they should be confirmed from the technical documentation for the specific MGK bearing.

LR 5202 2RS MGK dimensions

The principal dimensions are:

15x40x15.9 mm

where:

• d = 15 mm - bore diameter
• D = 40 mm - outside diameter
• B = 15.9 mm - bearing width

When selecting a replacement, all three dimensions should be verified. A matching 15 mm bore alone is not sufficient to confirm interchangeability.

What does 2RS mean?

2RS indicates that the bearing is sealed on both sides.

The seals help limit the entry of contaminants into the bearing and help retain lubricant around the rolling elements and raceways.

This can be particularly important in mechanisms operating near:

• dust
• small contaminants
• machine components
• guides and rails
• open conveying mechanisms

Seal suffixes and exact seal designs can vary between manufacturers. When comparing bearings from different brands, the sealing arrangement should therefore be checked rather than relying only on the 2RS suffix.

LR 5202 2RS as a track roller

An important feature of the LR bearing series is the ability to use the outside surface of the outer ring as a running surface.

This allows bearings of this type to function as guide or support rollers.

In this type of application, the outer ring does not simply sit inside a conventional housing. Instead, it can run directly against a suitably designed mating surface.

The performance of the complete system therefore depends not only on the bearing but also on factors such as:

• track geometry
• surface hardness
• surface finish
• alignment
• accuracy of the mating components
• operating load

These factors should be considered when designing or servicing a track roller system.

LR 5202 2RS vs standard 5202 bearing

Similarity in designation does not automatically mean identical construction or full interchangeability.

LR 5202 2RS is intended for applications characteristic of track roller bearings. Before replacing it with a standard 5202 bearing, verify:

• principal dimensions
• bearing width
• outer ring geometry
• internal design
• sealing arrangement
• support method
• operating loads
• interaction between the outer ring and the track

A replacement should not be selected solely because both products contain the designation 5202.

How to select a replacement for LR 5202 2RS

Before using a replacement bearing, verify:

• LR 5202 2RS designation
• 15 mm bore diameter
• 40 mm outside diameter
• 15.9 mm width
• double row construction
• outer ring design
• running surface geometry
• sealing arrangement
• required load capacity
• operating speed
• mounting arrangement
• interaction with the guide or track

Dimensional compatibility alone does not always guarantee functional interchangeability.

Typical applications of LR track roller bearings

Bearings and track rollers of this design group can be used in guiding and rolling mechanisms such as:

• linear guiding systems
• sliding and travelling mechanisms
• conveyor equipment
• material handling systems
• packaging machinery
• industrial automation
• production machinery
• component guiding systems
• roller mechanisms
• special-purpose machinery
• maintenance applications

These are typical applications for the product category and do not confirm the suitability of LR 5202 2RS MGK for a specific machine or installation.

Installation of LR 5202 2RS

During installation, mounting force should not be transmitted through the rolling elements.

Where the bearing is mounted onto a shaft, the mounting force should be applied to the appropriate bearing ring.

Good installation practice also includes:

• keeping the bearing and surrounding components clean
• protecting the seals from damage
• avoiding direct hammer impacts
• checking the condition of the shaft
• checking alignment
• inspecting the mating track or guide surface
• observing the permitted operating parameters

Where the outer ring runs directly against a track or guide, the condition and geometry of that surface can have a significant influence on the operation and service life of the complete system.

What does LR mean?

LR identifies a bearing series used for track roller and guide roller applications, where the outer ring can operate against a suitably designed running surface.

Is LR 5202 2RS a double row bearing?

Yes. LR 5202 2RS has a double row construction.
