FK FKN Series Sprag Type Freewheel Clutch FKN 6205-2RS One Way Bearing

Data Sheet

Components

Drawing legend:

d = inner diameter D = outer diameter W = width r = edge radius T = torque n = rotation speed C = load capacity

The specified nominal torque is based on sufficient stiffness of mating parts.

Rotation speed n for series FKN (without seals) = assembly unit's inherent speed

Rotation speed n for series FKN 2RS (with seals) = speed difference of mating parts.

Supplementary Introduction

Operating temperature

max. 140°C

Higher temperatures on request

max. 110°C (design 2RS with RS seals)

Lubrication

Series FKN 2RS with seals

Operative lifetime grease lubrication

Series FKN without seals

Oil or grease lubrication

Delivered with corrosion protection.

Installation

Installation tolerances

Shaft n6; hub N7

Mating parts

Hardening and grinding of the mating parts is not necessary. Thoroughly clean (grease free) the mating parts in the vicinity of the freewheel clutch as well as the freewheel clutch's rings before making the press fit.

Bearing

The freewheel clutch includes ball and roller bearings. Additional external bearing support is not necessary.

Press fit pressure

Press fit pressure must not be applied to the balls.

Clamping direction

The arrow on the inner ring designates the inner ring's clamping direction.

Seals*

The RS Seals reliably seal out grease and dust but are not suitable to protect against permanent higher liquid levels.

Series FKN 6203-RS has an RS seal on one side only (RS Seal on the freewheel side).
