SKF Spherical Roller Bearing， 140 mm ID， 250 mm OD - 22228 CC/C3W33 This spherical roller bearing from SKF is a self-adjusting unit that effectively accommodates shaft misalignmentIt delivers even load distribution and has a very high load-carrying capacity for heavy-duty applicationsIts innovative self-guiding rollers keep friction and heat at low levels， so your equipment can operate efficientlyThis lack of friction also reduces wear on the bearing， ensuring a long lifespanThanks to its steel construction， its highly durable and resistant to corrosion， so its suitable for use in harsh environmentsA bearing like this is used in applications with heavy radial and axial loads in either direction. Suitable to use with compact machinery as its simple to mount in tight spaces Substantial fatigue load limit of 86.5 kN Supplied as a non-separable bearing for simple and time-saving installation Reduced maintenance and service costs due to low consumption of lubrication Application Information Wind power generation Medical and pharmaceutical manufacturing Off-shore drilling Pump manufacturingSKF 球面ローラーベアリングには、2 列の対称ローラー、共通スフィンベアリング外輪軌道、ベアリング軸に対して傾斜する 2 つの内輪軌道があります。外輪軌道の球の中心点は、ベアリング軸にあります。内径 140 mm、外径 250 mm です。 Does this bearing need maintenance ベアリングはスチール製です 円筒穴タイプThe bearing is wear-resistant and wont need frequent maintenance or replacementIt has three lubrication holes on the outer ring for simple re-greasing when necessary.
