Reduced maintenance: NTN-SNR sealed spherical roller bearings do not require maintenance under normal operating conditions. In cases of high speed and temperature relubrication may be necessary. In the standard version, the bearings are delivered with a groove and lubrication holes (suffix W33) that allow for relubrication. Please consult our experts who will define the relubrication conditions specific to your application. Designations Cylindrical bore Fitting dimensions

Technical characteristics Load capacities: Identical to the open bearings of the ULTAGE series Speeds: According to a general principle, the limiting operating speeds for sealed spherical roller bearings are lower than those of open bearings. They depend on operating conditions (load, temperature), type of seal, quality and quantity of grease used. For normal operating conditions, the limit speeds are provided in the product table. Misalignment: Constant contact pressure of the seal even in case of misalignment. NTN-SNR sealed spherical roller bearings accept misalignments of up to 0.5° without...
