Which block is right for your application: plain bearing, ball bearing or roller block?
Wichard blocks, whether plain bearing, ball bearing, stainless steel or roller, are widely used in industrial applications.
At Wichard, 5 main families of blocks are available. Each range offers specific advantages:
- Plain bearing blocks: with a sheave rotating on a stainless steel shaft, these are used for static manoeuvres (relatively restricted movement) for high loads
- Ball bearing blocks: equipped with two rows of Delrin balls. These are ideal for dynamic manoeuvres (wider movement)
- Roller blocks: by replacing the balls with rollers, these pulleys can also withstand heavy loads during dynamic manoeuvres
- Friction blocks (i.e friction rings): without a rotating sheave, these are mainly used for static manoeuvres with heavy loads
- Stainless steel blocks: these small blocks are ideal for applications requiring low loads, small space requirements or low unit weight.
Wichard blocks are available with a variety of endings (shackle, clevis, etc.) for easy integration.
