NTN spherical roller bearing are consist of inner ring,outer ring,rollers and cage,the barrel rollers track along two row of raceway grooves in the inner ring,The center of the outer ring’s raceway aligns with the center of the bearing. this kinds of bearing can self-aligning so it can accommodates the errors in housing assembly and misalignments between the inner and outer rings caused by bent shafts. NTN Spherical roller bearing have a large load capacity and suitable for many application with vibration and impact loads.
NTN self-aligning roller bearing have the cylindrical bore and tapered bore,the tapered bore have K and K30 design,the spherical roller bearing with tapered bore can be mounted using an adapter or removable sleeves,NTN self-aligning roller bearing have brass cage and pressed steel cage design,The NTN unique design leads to:
1.Reduced friction torque (as much as 30% less), offering lower operating temperature, with lower power and lubricant consumption.
2.Appreciably increased operating speed, allowing an extended scope of applications.
3.High temperature capacity of up to 200°C (392°F) for metallic cage bearings. Dimensional stability is ensured by a specific heat treatment.
4. A +/- 0.5° misalignment capability, without reducing the load capacity, and up to 1° 30’ in case of low loads
FREQUENTLY ASKED QUESTIONS ABOUT NTN SPHERICAL ROLLER BEARING
1.What is the difference between B-type and E-type of spherical roller bearings ?
The B-cage spherical roller bearing has asymmetric rollers guided by an inner ring center rib for better skewing control. E-cage spherical roller bearing employs larger symmetric rollers for increased load capacity, fast becoming the industry standard. With the recent acquisition of SNR, NTN can provide more E-type spherical roller bearings than ever.
2.Does NTN produce sealed spherical roller bearings and self-aligning roller bearings?
NTN manufacture a limited series of sealed spherical roller bearings and self-aligning roller bearings, the WA22200 series, the MX-W22200, and more special sealed spherical roller bearings. Please contact XRB-engineering for more details.
