THKSR35W1SSRadial-Biased LM Guide Carriage Block, Size 35 for 34 mm Rail, 48 mm Height, 90° Contact Angle, C 60.4 kN, GK Interchangeable Series, Block Only

Product Description

What this part is:

THK SR35W1SS(GK) LM Guide carriage block, model SR35W: a four-row linear bearing block for a 34 mm wide SR size-35 LM rail. Block only, from the GK interchangeable series. Unit Quantity: 1 Pc. The SR series uses a 90° contact angle, where the HSR series uses 45°.

Decoding the designation:

SR — THK’s radial-biased LM Guide series, 90° contact angle.

35 — size, corresponding to a 34 mm wide rail.

W — block type, bolts mounted from above. The companion type is SR35V.

1 — THK’s coding field for the number of blocks used on the same rail.

SS — end seal plus side seal.

GK — THK’s interchangeable block and rail series: blocks and rails with the same model number combine freely.
