2301 Bearing, widely use, high speed rotation

Model Number: 2301 Brand Name: BMT Key Specifications/Special Features: Self-aligning ball bearing profile: Thisbearings have two balls and a common concave spherical outer raceway. Therefore bearings are self-aligning, from shaft relative to the bearing box not affected. It is particularly applicable to those that may produce relatively large shaft deflection or misalignment bearing applications. In addition, self-aligning ball bearings in all rolling bearing friction minimum, so that even at high speed to maintain a lower temperatureThere are several design self-aligning ball bearings:Basic design of the open bearingSealed bearingsOpen bearings

Self-aligning ball bearing products:

• Basic design: The basic design of the self-aligning ball bearings with a cylindrical bore with a tapered bore (conical 1:12), or within a certain size range. The 130 and 139 series of large, self-aligning ball bearing was originally developed for the paper mill's specific occasions, but can also be used for the importance of low-friction higher than the load capacity of the occasion. The bearing outer ring and the inner ring has an annular groove and several lubrication hole, the inner ring lubrication aperture. Highlight some of the 12 and 13 series of steel ball bearings from the side of the bearing. The overall width of these bearings (through ball) is listed in the bearing table, and should be considered in the related parts of the design of the bearing arrangement
• Seal design: Self-aligning ball bearings with sealed contact seals on both sides of the bearing - Model suffix 2RS1. These enhancement type seal of the thin steel sheet made by the oil resistant and abrasion resistant nitrile butadiene rubber (NBR rubber). These seals allowable working temperature range from -40 to +100 degrees Celsius can also allow a short time up to a temperature of +120 degrees Celsius. The seal lip light pressure contact with a smooth chamfer on the inner ring. Standard sealing grease lubricated bearings with a lithium-based thickeners based, having a good anti-rust properties and other characteristics Sealed self-aligning ball bearings with cylindrical holes. Some dimensions are also available with a tapered bore (conical 1:12)
• Self-aligning ball bearings with extended inner ring: The self-aligning ball bearings with extended inner ring is designed based on the use of commercial-grade shaft low requirements occasions. The special hole tolerances makes detachably easy. With extended inner ring, self-aligning ball bearing with a pin or with block shoulder screws to the axial positioning interlocking with a slotted shaft, pins or screws in the inner side, as well as to prevent rotation of the inner ring on the shaft. Two with extended inner ring, self-aligning ball bearings supporting a shaft position they should let the inner ring slotted either face-to-face, or at the outside of the bearing
