DUB-LITE® 00503 Series

Type 2 - Clevis / Clevis

dub-lite-00503-series-1-.jpgThe swivels feature a multiple sealing system which is progressive in design and application. Swivels 00503-204 to 00503-215 include a side mounted grease nipple for easy access without having to remove the clevis pin. Greasing should be done after each use.

The DUB-Lite® swivels utilize angular contact bearings for both pullback and pushback functions. All mechanical components are manufactured from high strength alloy steel and are designed to withstand a straight tensile load of at least 3 times the safe working load. The simplicity of this swivel allows field re-building, and a re-build kit comprised of bearings and seals is available.

The DCD Clevis Pin is specifically designed, machined and heat treated to provide the required strength and stability of the clevis. The clevis pins are hardened steel
and are available as replacement kits. These clevis pins must not be replaced with simple hexagon bolts.

The clevis/clevis style of swivel is the most common type and is the best for distributing side loads applied on the swivel due to its ability to pivot at either end. It does not allow the operator to push back without proper care and attention or the swivel may fold back on itself. Before rotation is re-commenced, the line must be pulled straight or damage may occur to the swivel, as well as potential harm to nearby operators.

DCD recommends that some type of restrictor be used to prevent the swivel from pivoting at the front or reamer end. For swivels 00503-204 to 00503-215, the clevis is deeper at the leading end to allow the fool-proof design of a lug that would prevent more than minimal movement of the swivel away from the axis of rotation and also ensures the swivel is pulled in the right direction. 

It is our recommendation to always select a swivel larger than the machine capacity.
