SPKVS / DSPK – Flanged wheel and castor series

Solid steel flanged wheels

The wheels in the SPKVS and DSPK series are made from high-quality machined rugged grey cast iron. Due to their hardness of 190 - 230 HB, the wheels provide excellent rolling resistance. The wheels are also wear-resistant.
The wheels in the SPKVS series have a rail profile which meets the requirements of crane rail standard DIN 536.
The DSPK series has a V-shaped tread.

The flanged wheels are frequently used as guide wheels or pulleys. However, they are also used for machine and systems engineering applications.

SPKVS / DSPK – Wheels

The wheels in the SPKVS series are available in sizes between 2 and 15 ³⁄₄ inch. The DSPK wheel series is available in sizes between 2 and 8 inch. All of the wheels in both series are fitted with a ball bearing. The SPKVSN series can be used as a drive wheel.
