M12 Bolt Hole Castors 5 Inch TPR Caster Wheel 125mm Custom Made

Features

• Wheel Diameter: 5 inches – A versatile size that balances smooth rolling over obstacles with a compact footprint.

• Mounting Type: Bolt Hole – Features a centered hole in the swivel section (typically 1/2" diameter) designed to accept a bolt or a custom stem, offering flexibility for various mounting requirements beyond standard top plates .

• Wheel Material: Thermoplastic Rubber (TPR) tread permanently bonded to a polypropylene or polyolefin core .

• Tread Design: Available in flat or round (donut/crowned) profiles. The rounded "donut" style reduces tread surface area for easier swiveling and improved maneuverability .

• Bearing Type: Precision ball bearings in the wheel hub for smooth rolling, combined with double ball bearing raceways in the swivel head for effortless rotation .

• Construction: Typically features a zinc-plated steel frame (or optional stainless steel) for corrosion resistance and durability .

• Hardness: Usually rated around 75-90 Shore A, providing a balance of softness for grip and durability .

• Temperature Range: Generally performs well in a wide range, from -40°F up to 180°F .

Functional Benefits

• Hybrid Performance (TPR Material): Combines the durability and chemical resistance of a hard plastic wheel with the quiet, shock-absorbing, floor-protecting qualities of a soft rubber wheel .

• Versatile & Flexible Mounting (Bolt Hole): The bolt hole design allows for custom installation on equipment that doesn't have a standard top plate pattern, or where a specific stem length is required .

• Superior Floor Protection (Non-Marking): The TPR tread is guaranteed non-marking and will not scuff or damage sensitive floors like tile, hardwood, epoxy, or sealed concrete .

• Quiet & Smooth Operation: Absorbs vibration and noise, providing a cushioned, quiet ride even over uneven surfaces or debris . The double ball bearings ensure easy rolling and reduced operator fatigue .

• Excellent Chemical & Moisture Resistance: Resistant to water, acids, bases, alcohols, salts, cleaning chemicals, and steam. This makes it ideal for wash-down environments and outdoor use .

• Impact & Flat-Spot Resistance: The TPR material resists flat-spotting under load and provides superior impact resistance, extending the wheel's lifespan .

Ideal Applications

The combination of TPR's floor-friendly properties, chemical resistance, and flexible bolt-hole mounting makes this caster suitable for a wide range of industries and environments:

• Institutional & Medical: Ideal for hospital beds, medical equipment carts, food service trays, housekeeping carts, and laundry carts where quiet operation, floor protection, and resistance to cleaning agents are critical .

• Material Handling & Industrial: Perfect for platform trucks, warehouse carts, welding carts, drywall carts, dollies, and assembly line equipment that need to roll easily over shop floors and debris .

• Retail & Display: Suitable for display fixtures, signage stands, and retail shelving that require easy maneuverability for store reconfigurations without damaging floors .

• Food Service: Excellent for kitchen equipment, serving carts, and preparation tables due to its resistance to cleaning chemicals and suitability for wash-down procedures .

• Commercial & Janitorial: Used for freight terminal equipment, large waste bins, and maintenance carts that demand durability and easy rolling .

• Specialty Applications: Stainless steel versions with total-lock brakes are available for applications requiring strict hygiene and stationary stability, such as in pharmaceutical or laboratory settings .
