Japan Pack 2022
Our customer displays their new conveyer with our Saniline bearing units at Japan Pack 2022.
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.
The demo machine of Turkish distributor
Our Turkish distributor built the demo machine.
That represents how our sealing performs very well.
Open Covers for SRB units
OPEN COVERS FOR SRB UNITS
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.

Case Study : CX2SN15-065L
Steam Blowers of the textile manufacturer (1900RPM)
BEFORE
SN515
The surface temperature of the unit rises to 100°C (230° F) within two months of installation. The grease from the unit is changed every two months. The temperature decreases initially after greasing to 80°C (176°F) before starting to rise again.
They cannot change all the grease using a grease gun so they have to take apart the upper part of the housing and clean out all the old grease by hand. This process takes over two hours.
AFTER
CX2SN15-065L
The surface temperature of the units initially went up to 120°C (248°F) and then decreased to 80°C (176° F) after the excess grease was purged within 24 hours. The temperature since then has remained between 65°C (149°F) and 80°C (176°F).
They don’t need to worry about the temperature any more. The COC unit saves money in downtime, labor and the cost of the grease.
