Frequently Asked Questions
Q: What is the difference between CL 120177-XL and the standard CL 120177?
A: The CL 120177-XL uses Poly XL 97A polyurethane, which is harder and more wear-resistant than the standard CL 120177 at 95A durometer. The higher durometer rating reduces tread wear and extends caster life, particularly in high-use environments. Confirm your equipment originally specified the -XL variant before upgrading.
Q: What Clark electric lift trucks are compatible with the CL 120177-XL?
A: The CL 120177-XL is a Clark OEM idler caster suitable for Clark electric lift truck applications. The Poly XL 97A compound makes this variant ideal for heavy-use applications or facilities with extended operating hours. Check your truck model documentation to confirm whether the -XL version is appropriate for your specific equipment.
Q: What does the 97A Shore durometer rating mean for performance?
A: 97A Shore durometer indicates a harder polyurethane compound than standard 95A. Harder polyurethane resists compression and abrasion better, reducing tread wear and flat-spotting. The trade-off is a slightly stiffer caster, which can increase vibration on rough floors but improves longevity and load support.
Q: How long does the CL 120177-XL caster typically last compared to the standard version?
A: The Poly XL 97A compound extends caster lifespan by 20 to 40 percent compared to standard 95A polyurethane, depending on load and floor conditions. In heavy-use warehouses, this can mean 2 to 4 years of service before replacement is needed. Regular inspection remains essential to catch uneven wear or flat-spotting early.
Q: Is the CL 120177-XL suitable for cold storage applications?
A: The CL 120177-XL is a standard polyurethane idler caster rated for typical warehouse and light industrial duty. Polyurethane hardens in cold storage, which can increase brittleness. For cold storage environments, verify whether your equipment requires a specialized cold-rated compound or heated caster variant designed for sub-zero conditions.
