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

base platethreaded studelastic

Overview
Leveling swivel castors engineered for hygienic environments such as food processing, pharmaceutical production and cleanrooms. Stainless steel construction combined with a blue non-marking elastic tire ensures floor protection, easy cleaning and visual identification in high-traffic areas. Integrated leveling mechanism enables height adjustment for stable, vibration-reduced equipment positioning.

Main features

• Fork and structural parts in stainless steel (EN 1.4301 / AISI 304)
• Double ball bearing swivel head for smooth rotation
• Wheel centre made of polyamide
• Tread: blue non-marking elastic tire (polyurethane/elastomer) — Shore A 65
• Wheel axle: nut-mounted or plain bearing depending on version
• Bearing options: stainless roller bearing or sealed precision stainless ball bearing
• Integrated leveling mechanism (height-adjustable swivel castor)
