Product Description
For high-dynamic and high-precision screw jack systems-applications there are high-performance rod ends available for the connection of the screw jack. The backlash ball joint allows fast movements with adjustment of three rotatory variances. To avoid full loads onto the ball joint, high-performance rod ends should only be applied in anti-twist designs. Rod ends consist of an eye-shaped head with integral shank that forms a housing for a spherical plain bearing. As a rule, rod ends are available with left- or right-hand female (internal) or male (external) threads. The Rod End is a spherical slide bearing incorporating a spherical inner ring with precision and hardness equivalent to that of steel ball bearings. It provides very smooth rotating and oscillating motion without play.
Double Clevis Screw Jack: The screw jack can be furnished with a clevis at both ends (commonly referred to as a double clevis screw jack). The bottom clevis is welded to the bottom end of an extra strong cover pipe, which is fitted to the base of the screw jack. This cover pipe still performs its primary function of encasing the lifting screw in its retracted portion. The clevis ends can be replaced with other pivot options such as Fork End or Rod End.
Clevis - Trunnion Mounting The screw jack is fitted with the pivot end fitting (e.g. Clevis, Fork or Rod End) on the lead screw and a trunnion mount adapter is bolted to the screw jacks base plate. The design of the structure in which these types of screw jacks are to be used must be constructed so that screw jack can pivot at both ends. Use only direct compression or tension loads, thereby eliminating side load conditions.
