INARNA22062RSYoke Type Track Roller – 35 mm Roller Bore, 62 mm OD, 19.8 mm Width, Lip Seals Both Sides, Crowned Outer Ring

Product Description

What this part is

INA RNA22062RSX is a yoke type track roller. Bore Diameter: 35 mm, measured over the needle roller complement. Outside Diameter: 62 mm. Overall Width: 19.8 mm (25/32 in). Rolling Elements: Needle Roller. Number Of Rows: 1. Closure Type: Lip seals both sides. Bearing Material: Chrome steel. Item Weight: 0.28 kg (0.61 lb).

Decoding the designation

RNA — Needle roller and cage assembly inside the outer ring, running directly on the shaft or pin, with the inner ring supplied separately where one is wanted.

22 — Yoke type track roller series with a particularly thick-walled outer ring, sized to run against a rail or cam track.

06 — Size code.

2RSR — Lip seals on both sides, radial sealing action. The listing also carries the 2RS and PP forms of the same code.

What these specs mean in practice

Dynamic Load Rating: 17,100 N. Static Load Rating: 26,500 N. Speed on permanent grease lubrication: 1,400 rpm. Fatigue load limit, radial: 3,600 N. Lubricant: Grease.

The thick outer ring is the point of a track roller: it takes the concentrated line load of a rail or cam without deflecting into the rolling elements. The outer ring outside profile is crowned to a 500 mm radius, which keeps contact away from the ring edges when the track runs slightly out of parallel.

Series: RNA22. Base Number: RNA2206.

Mounting data

Pin or shaft seat 35 mm, hardened and ground, which is the raceway for the rollers. Minimum mounting dimension 43 mm. Outer ring width 19.8 mm. Minimum chamfer dimension 1 mm.

The matching separate inner ring for this size is the INA IR35x42x20.

Quantity and configuration

Unit Quantity: 1 Pc. Outer ring with needle roller and cage assembly and both lip seals.

Interchange guidance

Same-envelope equivalents: IKO NAST35ZZ in the corresponding yoke series and McGill MR series rollers of the same 35 x 62 envelope. Cross-references on yoke track rollers are deliberately few: outer ring crown radius and ring wall thickness vary between makers, and those are the features that decide whether a roller survives on a given track.
