K■Structure and FeaturesIKO L-Balls are self-aligning rod-ends consisting of a special zinc die-cast alloy body and a studded ball which has its axis at right angles to the body.Ball-studStructures of L-Ball LHSABodyThey can perform tilting movement, oscillating move-ment and rotation with low torque, and transmit power smoothly due to uniform clearance between the slid-ing surfaces.Their superior wear resistance assures stable accura-cy for long periods of time, and maintenance is sim-ple. They are very economical bearings.For these reasons, they are widely used in link mech-Bushing (Low carbon steel)LHSA 5, 6Bodyanisms in automobiles, construction machinery, farm Ball-studand packaging machines, etc.■TypesL-Balls are available in various types as shown in Table 1. Table 1 Type of L-BallsTypeL-BallModel codeLHSALHSL-Ball dust coverPRCL-Ball LHSAThese are compact rod-ends in which the spherical part of the ball-stud are held by the special zinc die-cast alloy body. There is a dust cover on the stud side and good quality lithium soap base grease is pre-packed. They can be run for long periods of time without re-lubrication and have excellent lubrication and anti-dust properties.As shown in the structural drawing, these rod-ends are classied into 3 types by size. In addition, the ball-studs of LHSA 10 and lower are formed in one solid body, but those of LHSA 12 and higher, which are used under large loads, have the stud friction-welded to a high precision steel ball to give greater resistance to wear.L-Ball LHSThese rod-ends have a friction-welded ball-stud, and a special zinc die-cast alloy body which houses the spherical surface of the high precision steel ball. There is an almost complete contact across the slid-ing surfaces, and the uniform clearance guarantees a stable bearing life.Dust coverand upwardsBall-studBushing(Copper alloy)BodyDust cover(Fixed to the body)Bushing(Copper alloy)Structure of L-Ball LHSBodyBall-studbase grease, they have excellent lubrication and anti-dust properties and can run for long periods of time without re-lubrication.An L-Ball dust cover can be attached to these rod-ends.
