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).
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.
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.
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.
Unit Quantity: 1 Pc. Outer ring with needle roller and cage assembly and both lip seals.
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.
Searchable forms of the number: RNA22062RSX, RNA2206-2RS-X, RNA 2206 2RS X, RNA2206-2RSR, RNA 2206.2RS, RNA 2206 PP, NA2206.
