What this part does and why you need it Durable polyolefin roller designed to deliver smooth, lownoise motion and long service life. Reduces wear and vibration in sliding and rotating assemblies, improving reliability and user experience. Compact size and standard bore make it an easy replacement part for many small machines and devices. Key benefits durability and long service life thanks to sturdy polyolefin construction. Smooth, lownoise operation for quieter equipment and reduced maintenance. Flexible sliding action and resistance to compression and wear extend component life. Clear compatibility: fits shafts with an 8 mm inner diameter and supports loads up to 50 kg (110.23 lbs). Specifications Material: Polyolefin Color: Black Inner diameter: 8 mm (0.31 in) Outside diameter: 40 mm (1.57 in) Thickness: 20 mm (0.8 in) Maximum loadbearing capacity: 50 kg (110.23 lbs) Features: Smooth motion, low noise, flexible sliding, compression and wear resistance Compatibility and fit Designed for applications that accept a 8 mm bore roller (fits 8 mm shafts). Standard outer and thickness dimensions suit a wide range of small transmission or guide roles. Practical use scenarios 1. Replacement roller in household appliances (e.g., sliding drawers, appliance doors) to restore quiet, smooth movement and reduce rattling. 2. Idler or guide roller in small mechanical assemblies such as instrumentation or electrical equipment, providing lownoise support and wear resistance under repeated motion. 3. Roller for recreational or lightduty items such as rollerskating shoe components or yoyo assemblies, where flexible sliding and low vibration are important. Typical applications Transmission components, instrumentation, electrical equipment Household appliances, internal combustion engines, transport vehicles Agricultural, construction, and engineering machinery Rollerskating shoes, yoyos and other small rotating or sliding devices Maintenance and handling Inspect periodically for excessive wear if used near the 50 kg load limit. when compression or surface wear affects smooth motion or increases noise. This roller provides a straightforward, durable replacement option for any assembly requiring an 8 mm bore, 40 mm outer diameter, and 20 mm thickness with reliable lownoise performance.
