Set of 4 - Pneumatic series steel centre wheels, fixed castors, load capacity each 150Kgs. Very go...Set of 4 - Pneumatic series steel centre wheels, fixed castors, load capacity each 150Kgs. Very good where delicate loads need to be protected or where a wider wheel is required such as in use travelling over playing fields. Item dimensions as follows: 260x85mm Pneumatic wheel, Plate Size: 135x110mm, Hole centre"s: 105x80mm, Bolt hole size: 10mm, Overall height: 320mm, Weight cap: 150kg per Castor (300kg set).
This guide is for users needing robust, gentle mobility for heavy loads, particularly on uneven or delicate surfaces. The Parnells 260mm Pneumatic Castor set offers exceptional shock absorption and weight distribution, ideal for protecting sensitive cargo and navigating challenging terrains like playing fields. A key caveat is their larger size, which requires adequate clearance for mounting and operation.

FAQs
What is the maximum weight capacity for the set?
Each castor has a load capacity of 150Kgs. A set of four castors can support up to 600Kgs, assuming even load distribution. For optimal performance and safety, it is recommended not to exceed 300Kgs per set of two or 500Kgs for a set of four.
Can these castors be used on indoor floors?
Yes, but they are best suited for industrial or workshop floors. The pneumatic tire can leave marks on very soft or delicate indoor flooring. They are particularly beneficial for indoor use if the floor surface is uneven or requires shock absorption.
Do I need to inflate the tires?
Yes, the pneumatic tires require air to function as intended and provide cushioning. Check and maintain the appropriate tire pressure regularly for optimal performance.
What size bolts should I use for mounting?
The bolt holes on the mounting plate are 10mm in diameter. You should use appropriately sized M10 bolts and nuts, ensuring they are long enough for your mounting surface and strong enough for the load capacity.
Are these swiveling castors?
No, these are fixed castors, meaning they only move in a straight line and do not swivel. This provides stability for heavy loads that do not require frequent directional changes.
How do I maintain the pneumatic tires?
Periodically check the tire pressure and inflate as needed. Inspect for any cuts or damage to the tire tread. Clean the tires with a damp cloth.
What is the overall height of the castor?
The overall height from the bottom of the wheel to the top of the mounting plate is 320mm.
Troubleshooting
Castor wobbles during movement.
Ensure all mounting bolts are securely tightened. Check that the wheel is properly seated on the hub and that the tire is evenly inflated. Verify the surface is not excessively uneven.
Uneven tire wear.
Check wheel alignment and ensure the load is evenly distributed across the castor. Inflate tire to the correct pressure. If the issue persists, inspect for bearing damage.
Difficulty rolling on soft surfaces.
Ensure tires are inflated to the higher end of the recommended pressure range. Distribute load evenly. Note that while designed for softer surfaces, extremely loose or deep terrain will naturally offer more resistance.
Steel components show signs of rust.
Clean the affected area and apply a rust inhibitor or paint suitable for metal. Ensure the castors are stored in a dry environment when not in use.
Larger physical size requires more installation space.
Fixed castors limit maneuverability compared to swivel types.
Pneumatic tires may require occasional inflation.
Not ideal for smooth, polished surfaces where precision turning is needed.
Setup, Compatibility & Care
Setup:
Mounting Plate: The 135x110mm top plate has four bolt holes (10mm diameter) spaced at 105x80mm centers. Ensure your equipment or structure has a sufficiently strong and flat surface to accommodate this plate.
Fastening: Use appropriate M10 bolts and nuts (not included) to securely fasten the castor to the mounting surface. Ensure all fasteners are tightened properly.
Clearance: Verify that the overall height of 320mm and the 260mm wheel diameter allow for adequate clearance under your equipment, especially when loaded.
Compatibility:
These castors are designed for fixed mounting applications. They are compatible with equipment requiring stable, non-swiveling directional movement.
Ideal for surfaces ranging from concrete and asphalt to grass and packed earth, where shock absorption is beneficial.
Care:
Tire Pressure: Periodically check the air pressure in the pneumatic wheels. Inflate as needed to the recommended pressure (consult wheel manufacturer if specified, typically around 30-50 PSI for similar wheels) to maintain optimal cushioning and load capacity.
Cleaning: Wipe down the steel components and wheel rims with a damp cloth to remove dirt and debris. Avoid abrasive cleaners that could damage the finish.
Lubrication: The wheel bearings may require periodic lubrication. Consult specific maintenance guidelines if available for the exact bearing type.
