摘要： PROBLEM TO BE SOLVED: To obtain a structure capable of preventing abrasion generated in a cage from becoming excessive even if the bearing pressure of a sliding contact part between respective spherical rollers and the cage increase, when the respective spherical rollers skew in operation.
SOLUTION: This cage 4b is formed of carbon steel (S25C, S48C : HV450 to 600). Thus, a hardness difference between the cage 4b and the respective spherical rollers 3 and 3 formed of hard materials such as high carbon chrome bearing steel (SUJ2 : HV670 to 770, SUJ3 : HV640 to 750) is reduced. As a result, even if the bearing pressure of the sliding contact part between the cage 4b and these respective spherical rollers 3 and 3 increases, the abrasion generated in the cage 4b can be restrained, and the problem can be solved.

摘要：高速回転時における軸受の発熱を抑制できるとともに、十分な剛性及び強度を確保できて高速性能に優れた合成樹脂製保持器を備えた円筒ころ軸受及び複列円筒ころ軸受である。円筒ころ軸受は、軸方向一端部に配置された円環部と、円環部の側面から延びた複数本の柱部とを有する合成樹脂製保持器を備える。円環部の最小内径d1を柱部の最大内径d2より小さくし、且つ、柱部の全長の2/3以下の長さの範囲で柱部の内径を円環部の内径d1と同一にした。複列円筒ころ軸受は、隣接する2本の柱部の円周方向両側面と円環部の内側面とによって三方が囲まれた複数のポケット部に外輪と内輪の間に転動自在に配設された円筒形転動体を複数列にわたって夫々回動自在に保持する合成樹脂で一体に形成された保持器を備える。保持器が回転時の遠心力によって弾性変形することで発生する部材同士の干渉を防止するために、予め干渉部位の形状を前記弾性変形分削除してテーパ形状に成形した。
