Timken VAK 3/4 Pillow Block Bearing

This new Timken VAK pillow block bearing is a cast-iron mounted unit with a 3/4 inch cylindrical bore. It uses an eccentric locking collar to secure a radial ball insert made from alloy steel. The housing measures 5 inches in overall length and 2.468 inches in overall height with a base height of .468 inches.

Suits shafts needing eccentric locking

Builders who need a double-sealed, bolt-through unit rated from -65 to 200 degrees F will find the specifications match. The NGLI #2 equivalent lubricant and two-hole mounting pattern on 3 49/64 inch centers fit standard industrial layouts. Buyers who require a different bore size, a set-screw locking method, or a housing material other than cast iron should look at other options.

Eccentric locking collar on a 3/4 inch bore

The single specification that decides fit is the eccentric locking mechanism combined with the 3/4 inch cylindrical bore diameter. This locking style grips the shaft by rotating the collar relative to the inner ring, which differs from set-screw or adapter-sleeve types. Verify the shaft diameter and the preferred locking method before ordering.

Questions about this item

How much heat can the cast-iron housing and NGLI #2 lubricant handle during continuous operation?

The bearing is rated for a maximum temperature of 200 Degrees F and a minimum of -65 Degrees F, so the housing and factory-fill grease remain stable across that range.

What mounting hardware and shaft size are required to install this pillow block?

You need a 3/4 in cylindrical shaft, two bolts for the 3 49/64 in center-to-center mount holes, and a flat surface that matches the 1 1/4 in center height.

Will the 3 49/64 in bolt spacing and 1 1/4 in center height line up with older Timken pillow blocks I already have?

The mount-hole centers measure 3 49/64 in and the center height is 1 1/4 in; compare those dimensions to your existing units to confirm interchangeability.
