The 3" Rigid/Swivel/with Brake Smooth Glide PP Caster Wheel is a medium-duty solution tailored for environments needing balance between load support (90-140KGS) and maneuverability. Made with polypropylene (PP) wheels and a double-bearing system, these casters glide smoothly across concrete, tile, and wood surfaces—ideal for industrial carts, medical supply trolleys, and retail shelving. Available in rigid, swivel, and swivel-with-brake types, the grey PP finish hides minor scuffs, making it perfect for high-traffic areas like warehouses, hospitals, and workshops.
Wheel Material: High-density PP with impact resistance—resists acids, alkalis, and cleaning chemicals, suitable for labs and food processing plants.
Double-Bearing System: Reduces rolling resistance, enabling easy steering of fully loaded carts (up to 140KGS) and minimizing operator fatigue.
Brake Mechanism: Swivel-with-brake models feature a locking brake that secures both the wheel and swivel joint—preventing accidental movement in busy spaces.
Wheel Specs: 3" (75mm) diameter, 32mm tread width, 85-90 Shore A hardness—balances mobility and load capacity.
Color & Code: Grey (wheel code: 313－2G) with a matte finish, blending with industrial and commercial equipment.
Mounting Plate: 96*66mm plate (75*45mm inner dimensions) with 8.5mm holes—fits standard cart frames, installs with common tools.
Medium-Duty Reliability: Supports 90-140KGS, ideal for workshop tool carts, hospital supply trolleys, and retail display units—no overkill for lighter loads.
Chemical Resistance: PP material withstands sanitizers, acids, and alkalis—safe for food processing and laboratory use.
Quiet & Smooth Movement: Double bearings and PP tread reduce noise, creating a calmer environment for hospitals or offices.
Floor-Friendly: Non-marking PP wheels won’t scratch tile or wood—suitable for finished floors in retail stores or clinics.
Low-Maintenance: Sealed bearings prevent dust ingress, eliminating lubrication needs—simply wipe wheels clean for upkeep.

A: The brake locks both the wheel and swivel, keeping equipment secure even on slight inclines (e.g., warehouse ramps).
A: Yes—PP resists acids and alkalis, making them suitable for labs or food plants where chemical exposure is common.
A: The 90KGS model (2.5" / 63mm diameter) works for small tool carts or lab reagent trolleys—prioritizing maneuverability.
A: They glide smoothly on low-pile carpet; high-pile carpet may reduce mobility (opt for larger wheels for thick carpet).
