XS2SN
SN Pillow Block Units ZS2P
XS2P
2-Bolt Base Pillow Block Units


ZS2SN is patented Z LOCK spherical roller bearing unit with SN style housing for the replacement of SN plummer blocks.

XS2SN has the same housing dimensions as the above styles but utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place.


ZS2P is a two-bolt pillow block unit with a Z LOCK locking system.  This unit is equivalent to many of our competitors SRB style housings. The ends of the housing are milled flat to allow for mounting inside of a fixed frame assembly.

XS2P has the same housing dimensions as the above styles but utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place.
Available from  40mm to 100mm sizes with a ductile iron housing standard. Available from  40mm & 1-3/8" to 100mm & 4" bore sizes with a ductile iron housing standard.

2-Bolt Base Type E Pillow Block Units

ZS4F
XS4F
4-Bolt Flange Units



ZSE2P is a two-bolt base pillow block unit with Type E mounting dimensions. It has a footprint that can accommodate both a tapered roller unit and a spherical roller unit for most shaft sizes.

XSE2P has the same housing dimensions as the above styles but utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place.



ZS4F is a four-bolt flange unit with standard spherical roller unit mounting dimensions and a compact footprint for areas with limited space.

XS4F has the same housing dimensions as the above styles but utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place.

Available from  40mm & 1-3/8" to 100mm & 4" bore sizes with a ductile iron housing standard. Available from 40mm & 1-3/8" to 100mm & 4" bore sizes with a ductile iron housing standard.

4-Bolt Type E Flange Units XS4FC
ZS4FC
Flange Cartridge Units


ZSE4F is a four-bolt flange unit with Type E tapered roller unit mounting dimensions. This makes for easy replacement of Type E units when the features of a spherical roller unit are more desirable.

XSE4F has the same housing dimensions as the above styles but utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place.

ZS4FC is a flange cartridge unit with pilot mounting dimensions that are the same as medium duty ball bearing units for easy upgrading to a heavier duty series. The threaded withdrawal holes allow for quick and easy dismounting.

XS4FC has the same housing dimensions as the above styles but utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place.
Available from 40mm & 1-3/8" to 100mm & 4" bore sizes with a ductile iron housing standard. Available from 40mm & 1-3/8" to 100 mm & 4" bore sizes with a ductile iron housing standard.

4-Bolt Base Pillow Block Units



ZST is a take-up unit with rail slots that are compatible with many industrial frame sizes. This unit can safely handle high belt tension and heavy shock loads.

XST has the same housing dimensions as the above styles but utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place.



ZS4P is a four-bolt base pillow block unit with standard spherical roller bearing mounting dimensions. Four mounting bolt-holes create a firm and secure fit to the mounting surface. The ends of the housing are flat to allow for mounting inside of a fixed frame assembly.

XS4P has the same housing dimensions as the above styles but utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place.
Available from  50mm & 1-15/16" to 90mm & 3-1/2" bore sizes with  a ductile iron housing standard. Available from 60mm & 2-7/16" to 100mm & 4" bore sizes with a ductile iron housing standard.

XDS4P
4-Bolt Base Pillow Block Units ZS SRB INSERT


ZDS4P is the same as the ZS4P but utilizes a double lock. This insert has patented Z LOCK locking mechanism on both the front and back of the inner ring. This additional locking mechanism is helpful in applications where the bearing experiences some thrust loads on the inner ring that could cause a single locking unit to slip.

XDS4P has the same housing dimensions as the above styles but utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place.

ZS is a Z-LOCK concentric locking insert that utilizes a tapered collar that allows for fast mounting while avoiding damage to shafting that a setscrew unit can cause. The tapered collar keeps the 100% true concentric holding
power and does not remove any clearance in the insert by over tightening like the adapter sleeve locking system can. The unit is tightened down using a hex wrench on the cap screws in a star pattern. The insert can be uninstalled by removing all cap screws and using two of them in the withdrawal holes to disengage the collar.

Available from 60mm & 2-7/16" to 100mm & 4" bore sizes with a ductile iron housing standard.  
XS
SRB INSERT ZDS SRB INSERT
XS is a setscrew locking insert that utilizes the patented
Bullet Point setscrews at 120 degrees apart to hold shafting firmly in place. This is the most economical type of SRB insert and can be utilized in a wide variety of
industrial and agricultural applications.

ZDS is the same as the ZS above but utilizes a double
lock. This insert has a concentric tapered collar on both the front and back of the inner ring. This additional
locking mechanism is helpful in applications where a bearing experiences some thrust loads on the inner ring that could cause a single locking unit to slip.
XDS SRB INSERT  
XDS is the same as the XS above but utilizes a double lock. This insert has a setscrew locking mechanism on both the front and back of the inner ring. This additional locking mechanism is helpful in applications where the bearing experiences some thrust loads on the inner ring that could cause a single locking unit to slip.
