Description
5x10x4 bearings used in the Kyosho Inferno MP9, MP777 WC and STRR, GT, ZX-5 kit and Readyset, GT2, ST, DBX and MP 7.5 series for clutch and Lazer ZX5 and Ultima RB5 and RB6 1/10th scales for Wheel bearings. Ultra high quality Japanese stainless bearings that last and last. Used in 1/8th scale clutches, which are very demanding on a bearing, they last many times longer than a Chinese or Taiwanese bearing. Just take them out of the clutch every 10-15 tanks of fuel and spray them out (clean them). Re-oil them with a light oil afterward using only 1 small drop and you are good for at least 10-15 more tanks of run time. These are a good choice if you are running your car in an endurance race (races more than 3 hours of solid run time). Infernosonly.com's racing team has run these bearings on a dusty track for 4 solid hours in a Buggy endurance race with no failures.
