Swivel caster Q-RND-3B-HSC-Mxx-Lxxx series

base platethreaded studtube

Product overview
Leveling swivel castors in hygienic design for sanitary industrial environments such as food processing, pharmaceuticals and biotechnology. Constructed with stainless steel components to reduce corrosion and minimise dirt-trapping areas. Polyamide wheel centre with blue polyurethane tread for non-marking, wear-resistant, water- and chemical-resistant performance. Integrated leveling mechanism provides stable positioning when equipment is stationary.

Design & materials

• Fork: stainless steel EN 1.4301 / AISI 304 (3 mm where specified)
• Wheel centre: polyamide
• Tread: blue polyurethane (Shore D 48)
• Bearings: stainless roller bearing or sealed precision stainless ball bearing; stainless plain bearing and double ball bearing swivel head options available
• Spindles and brackets: stainless steel EN 1.4301 / AISI 304

Key benefits

• Blue polyurethane tread: non-marking, abrasion-resistant, resistant to water, chemicals and cleaning agents
• Hygienic stainless steel construction: smooth, sealed surfaces for easier cleaning and sanitisation
• Built-in leveling mechanism: improves stability and reduces vibration when stationary
