New steel end covers

New steel end covers

Our Cathodic electrodeposition (CED) coating for our steel covers has excellent corrosion resistance and is environmentally friendly.  The laser marking however doesn’t have that same corrosion resistance.  As we don’t like to see the rusted sea turtle logo on the cover we changed it to a pressed logo of COC.  The sea turtle logo is just a bit too complicated for a pressed mold.

LOCK NUT vs CROSSLOC

LOCK NUT vs CROSSLOC

LOCK NUT vs CROSSLOC

The adapter locking engages by moving adapter sleeve. The tapered O.D. sleeve moves between the tapered bore inner ring and the shaft to hold the shaft in place. That is usually done by tightening the lock nut to push or pull the adapter sleeve.

It is very difficult to tighten the lock nut of wide inner ring unitized adapter locking systems. It’s sometimes almost impossible to tighten as per their instructions’ turns.

Our CROSSLOC is a lot easier to move the adapter sleeve by tightening cap screws. The possible reasons are below.

LOCK NUT

  • The adapter sleeve is very thin to keep the same size as a setscrew locking bearing. It can become distorted making it impossible to tighten.
  • The lock nut has a lot of contact area and it needs a lot of torque to turn.

CROSSLOC CX

  • The CX bearing is one size bigger than CS set screw lock bearing to accommodate the standard adapter sleeve.
  • Small cap screws are easy to tighten with a hex key. The force of pushing the adapter sleeve by tightening it in a star pattern is a lot larger than by tightening the lock nut.

Our bearings will last long and CROSSLOC™ nuts can rust sometimes by rain in outside applications.

The new open steel cover with V-ring seal will protect from the dirt and water. This new open cover is being added to our existing end closed covers and will protect better for those applications.

The molded rubber V-ring seal is press-fit on the shaft and rotates with shaft. The seal lip contacts on the cover not the shaft, so the shaft doesn’t get any damage from the seal lip.

Due to the tapered seal contact area of the open cover, the seal lip maintains full contact even when misaligned.

When the Open cover is used with the bearing with labyrinth seals for high speed, make a space between the seal lip and open cover to keep it from contacting. The V-ring seal will be an extra barrier as a flinger.

The open cover has the plugged drain hole and you can take the plug out for the labyrinth seal applications to drain ingressed water.

New open covers will be available from March 2022.
