Frequently Asked Questions
Q: What is SU 855 and what is it used for?
A: SU 855 is a load wheel for electric lift trucks. Without the full specification sheet, contact your distributor or supplier with the truck model and wheel position to confirm the exact dimensions, material, bore configuration, and load rating for your application.
Q: Is SU 855 a direct replacement for other wheel part numbers?
A: Cross-compatibility depends on the dimensions and bore configuration of SU 855, which are not fully listed. Before substituting SU 855 for another wheel part number, verify the outside diameter, width, bore diameter, and material specification. Confirm compatibility with your parts supplier or truck manufacturer.
Q: What is the correct procedure for installing SU 855?
A: Ensure the truck is lowered to the ground and safely supported before installing or removing wheels. Slide SU 855 onto the axle until fully seated. The wheel must spin freely by hand with no lateral play or binding when lifted. If installation is difficult or the wheel does not fit, check the axle diameter and condition.
Q: How often should SU 855 wheels be inspected?
A: Inspect wheels visually every 250 operating hours or monthly in high-use environments. Check for cracks, flat spots, uneven wear, and bearing noise. Replace wheels when the tread is worn flat, diameter has decreased noticeably, or the wheel no longer rolls smoothly.
Q: What factors determine the service life of SU 855?
A: Service life depends on load weight, floor surface condition, truck usage hours per day, and axle alignment. Typical replacement intervals range from 6 to 24 months. Rough concrete floors and heavy loads reduce lifespan. Proper truck maintenance and alignment extend wheel life.
Q: Where can I find the complete specifications for SU 855?
A: Contact the parts supplier or distributor with the truck manufacturer name, truck model number, and serial number. Provide the wheel position on the truck to receive accurate specifications, load rating, and cross-reference information for SU 855.
