LR5200 double-row track roller bearings with a thick outer ring

LR5200 TRACK ROLLERS

LR5200 Track Roller Bearings: Size Chart

LR5200 rollers are double-row angular contact track rollers based on 5200 sizes, with a thick outer ring. They carry more load and axial force than LR5000 rollers of the same bore. This page lists LR5200 to LR5208, 10 to 40 mm bore.

Typical applications: flat-track and cam roller linear guides, guide and idler wheels, woodworking and metal processing machines, packaging and handling machines, conveyors, and door and gate tracks.

How LR roller numbers are built

Number or suffix	Meaning	Example
LR52xx / LR53xx	Double row angular contact rollers based on 52xx / 53xx sizes	LR5204NPPU = 20 × 52 × 20.6
Last two digits	Same bore code as standard bearings: 04 = 20 mm	LR5204 → 20 mm bore
NPPU / KDDU / KDD	NPPU = rubber seals, crowned outer ring. KDDU = metal shields, crowned outer ring. KDD = metal shields, cylindrical outer ring. U marks the crowned outer ring.	LR5204NPPU, LR5204KDDU, LR5204KDD

Selection checks for track rollers

A crowned outer ring tolerates small misalignment and avoids edge loading. A cylindrical ring spreads the load over a wider line on a well-aligned track.
The track must be hard enough for the contact load. A soft track wears or dents before the roller.
Use an eccentric stud or adjustable mounting to set clearance against the track.
Choose seals for dust and coolant, shields for lower friction in clean places.

Custom track rollers

We make track rollers to drawing: special grooves, extended inner rings, non-standard widths, eccentric versions and polyurethane-covered rollers. Send the rail profile, shaft or stud size, load, speed and quantity, or an old sample.

Frequently asked questions

What is the difference between LR5004 and LR5204?

Both have a 20 mm bore. LR5004 is a single-row roller, 20 × 47 × 16 mm. LR5204 is a double-row roller, 20 × 52 × 20.6 mm, and carries more load and axial force.

Why does a track roller have a thick outer ring?

The outer ring runs on the track as a wheel. A thick ring does not bend under the concentrated contact load, so the internal ball raceway stays round.
