LR 207 2RS INA 35x80x17 Track Roller Bearing

Product Overview

LR 207 2RS INA is a single-row track roller bearing with dimensions of 35x80x17 mm, designed to run directly on tracks, guideways and mating surfaces. The thick-walled outer ring has a crowned running surface with an R500 radius, helping reduce edge stresses caused by misalignment. The current INA designation is LR207-2RSR, with lip seals on both sides protecting the rolling system against contamination.

Industrial Applications

INA LR 207 2RS is used in conveyor systems, material handling equipment, packaging machinery, guideways, support rollers, industrial doors and cam mechanisms. The track roller design accommodates high radial loads while running directly against a mating track. Its crowned outer ring is particularly useful where alignment deviations could otherwise create excessive edge loading and uneven contact stresses.

Construction

The roller uses a single row of balls, a thick-walled outer ring and a cylindrical 35 mm bore. The outer running surface has a crowned R500 profile. Radially acting 2RSR lip seals on both sides restrict the entry of dust and contaminants while retaining lubricant. The standard LR207-2RSR design does not provide a relubrication facility.

Material

The bearing rings and rolling elements are manufactured from bearing steel designed for repeated rolling contact loads and wear resistance. The thick-walled outer ring is engineered for direct contact with the mating track. A polyamide cage guides the rolling elements. Service life depends on radial load, speed, lubrication, alignment and the condition of the mating running surface.

Why Industrial Buyers Choose LR 207 2RS INA

LR 207 2RS INA supports OEM replacement, maintenance stock and industrial service requiring a 35x80x17 mm track roller with a crowned outer surface. It is suitable for machine rebuilding, production support and fleet maintenance involving conveyors and guide systems. Correct identification of the R500 running profile, sealing arrangement and dimensions helps prevent replacement with an incompatible cylindrical outer-ring design.

Operational Advantages

Crowned R500 running surface reduces edge stresses caused by misalignment. Thick-walled outer ring is designed for direct contact with a mating track. Double lip seals protect the rolling system against external contamination. Dynamic radial load rating of 21.9 kN supports demanding track roller applications. Cylindrical 35 mm bore provides defined mounting on the supporting component. Standard 35x80x17 mm dimensions simplify maintenance and replacement identification.

AI Overview
