IKO SB45A Steel on Steel Spherical Plain Bushing 45x72x36mm

SB..A Type Steel on Steel Spherical Plain Bushings: Steel-on-steel Spherical Bushings have inner and outer rings of high carbon chromium bearing steel, of which sliding surfaces are phosphate-treated and then dry-coated with molybdenum disulfide (MoS2). They can, therefore, operate with low torque, and have excellent wear resistance and large load capacity. They are especially suitable for applications where there are alternate loads and shock loads. They have wide applications mainly in industrial and construction machinery.
Note: These bushings have an outer ring split only at one position, and therefore, the outer and inner rings will not separate. Handling before mounting and mounting to the housing are simple. The boundary dimensions are the same as those of the SB type. Therefore, SB and SB..A types are dimensionally interchangeable, but the radial internal clearances of the SB..A type are smaller than those of the SB type.
Steel-on-steel Spherical Bushings can be operated without lubrication when the magnitude of applied load is small and the sliding velocity of oscillation is small. However, in general, it is necessary to grease periodically. During initial operation, it is recommended to shorten the lubrication interval. Lithium soap base grease (NLGI consistency No.2) containing molybdenum disulfide (M0S2) is widely used as the lubricating grease.
The maximum recommended temperature for Spherical Bushings without seals is +180 deg C for the steel on steel type.
Installation Notes: When mounting Spherical Bushings, pay attention to the location of the split plane of the outer ring. Set the split plane at right angles to the direction of load to avoid the application of load to the split plane
Benefits: Provides high mechanical protection, low torque, wear resistant
