This KOYO 6302RMX ball bearing is a high-quality replacement for Toyota and Lexus idler pulleys. The dimensions are 10mm inner diameter, 42mm outer diameter, and 13mm width – a common size for many Japanese cars. It's brand new, unopened, and made in Japan, so you know it's up to OEM standards.

The MPN is KOYO JAPAN 6302RMX, and the brand is KOYO, a trusted name in bearings. No UPC, but the part type is clearly a ball bearing. If your idler pulley is noisy, wobbly, or seized, replacing just the bearing can save you money over buying a whole new pulley.

Installation requires a press and some mechanical skill, but it's a straightforward job for a shop or experienced DIYer. Keep your engine accessories running smoothly with a genuine KOYO bearing. Reliable, durable, and built to last.
