Roller for industrial cart Blickle BKRA-TPA 101G, max load 275 kg, rubber tread, polypropylene wheel body, height 133 mm

The Blickle BKRA-TPA 101G is a light-duty fixed castor designed for trolleys and transport equipment. It combines a pressed steel BKRA-series bracket with a TPA-series wheel that has a thermoplastic rubber (TPE) tread and a polypropylene wheel centre. The castor is zinc-plated with blue passivation and is chromium(VI)-free. The wheel tread is non-marking grey, Shore A 85 hardness, and the wheel centre is silver-grey polypropylene with good impact resistance. The roller supports a maximum load of 275 kg and has an overall height of 133 mm.

Advantages

This castor offers chemical resistance to many aggressive substances and a non-marking thermoplastic rubber tread that provides quiet running and floor protection on suitable surfaces. The pressed steel bracket is zinc-plated and blue-passivated to resist corrosion, and the polypropylene wheel centre combines low weight with impact resistance. The design is suitable for straightforward replacement or upgrades on trolleys and carts.

Suitable for

• Light-duty trolleys and platform trucks in warehouses and workshops
• Transport equipment where non-marking, quieter wheels are preferred
• Applications requiring a compact castor with up to 275 kg load capacity

When it may not be suitable

This castor is intended for light-duty use; it is not designed for heavy industrial loads beyond the stated 275 kg limit. Operating temperatures below -20 °C or above +60 °C are outside the specified range, and load capacity is reduced above +30 °C. The tread contains oil and may stain sensitive or light-coloured floor surfaces.

Key specifications

• Type: fixed castor with bolt hole
• Bracket material and finish: pressed steel, zinc-plated, blue-passivated, Cr6-free
• Wheel tread material: thermoplastic rubber (TPE), hardness 85 Shore A, grey, non-marking
• Wheel centre material: polypropylene, impact resistant, silver-grey
• Maximum load capacity: 275 kg
• Overall height: 133 mm
• Operating temperature range: -20 °C to +60 °C (reduced load above +30 °C)
• Weight (approx.): 300 g

How to use

Install the castor by aligning the bolt hole in the BKRA bracket with the corresponding mounting point on the trolley or equipment and secure with the appropriate bolt and locking hardware for your application. Ensure the mounting fastener matches the bracket hole diameter and the equipment’s load-bearing capacity. After installation, check that the wheel turns freely and that the bracket is securely fixed. Regularly inspect the tread for wear and the mounting for corrosion or looseness; replace the castor if damage or excessive wear is found.

What to consider before purchase

• Verify that the 275 kg maximum load is sufficient for your application (per castor or per wheel position as specified by your equipment)
• Confirm mounting bolt diameter and hole spacing match your trolley or equipment
• Consider floor type—tread contains oil and may stain sensitive or very light-coloured surfaces
• Account for operating temperature range and reduced load capacity above +30 °C

Usage recommendations

For best results use the BKRA-TPA 101G on smooth, dry floors and avoid prolonged exposure to temperatures above +30 °C. If floor staining or higher chemical resistance is a concern, consider alternative wheel series such as VPA, VPP, POES, POEV or PATH. Periodic inspection and correct mounting hardware will extend service life.
