WRC MN

Standard block, available both with and without ball chain. Versions with ball chain are indicated with …C in the designation in the table below.

The use of ball chain reduces the number of balls carrying the load. For high load applications or any application where severe chock-loads may occur, the standard version offers better safety margins by its higher static limit (C0).

For light to medium loads where a very long lifetime is required, the ball-cage will show superior life span and reliability.

Please note that ball chain versions must never be used for linear speeds exceeding 3 m/s!

Dimensions in mm.

Lead times in the table below are only indications. Choice of preload, accuracy class and other options will affect lead time. Please contact us for exact delivery time for your request.
