Abstract
【解決手段】外輪1と内輪11との間に合成樹脂から成る保持器21を組込み、その保持器21に形成されたポケット23内にボール31を収容する。ポケット23を円筒形とし、その円筒形内面24の保持器周方向の前後で対向する位置の内径側端部に一対の円錐面40を設け、その円錐面40の小径端からポケット内方に向けて潤滑剤支持面41を連設し、その潤滑剤支持面41の内側にボール案内される直線状のボール案内縁42を設け、保持器21の軸方向への移動時に、ボール31をボール案内縁42に沿って移動させて保持器21に径方向のスラスト力が付与されるのを防止し、保持器21が振れ回るのを防止する。
【選択図】図10
Description
ボール31の外径D1=8.7313mm
保持器21の外径D2=67.7mm
保持器21の内径D3=62mm
ポケット23の内径d1=9.0mm
