NSK pillow block bearing

A pillow block, also known as a plummer block[1] or bearing housing, is a mounted plain or roller bearing used to provide support for a rotating shaft with the mounting surface on a parallel line with the axis of the shaft. Housing material for a pillow block bearing is typically made of cast iron or pressed steel. Pillow block bearings are extensively used in conveyor systems such as tube chain conveyors. Most pillow block bearings are self-lubricating.

Outer spherical bearings with pillow block can work with two pillow blocks of different shaft, the maximum self-auto-adjustable angle is 2°. We take “ten” tolerance to measure the inner diameter of pillow block outer spherical bearings, which form the clearance fit under the performing with shaft. Though the jack bolt on one side of the inner ring, eccentric sleeve or adapter sleeve fastens the bearing on the shaft to reduce the accuracy requirement of the shaft, then quite convenient to install Generally, pillow block outer spherical bearing is the pre-filled lubricant grease, which takes double-layer sealing, adapt to the conditions of power, mud water and corrosive medium, and is beneficial for the machine to work.

Pillow block outer spherical bearing has the excellent rotational accuracy, so that it can be re-lubrication conveniently. The windage on it is bigger than on the same-size deep groove ball bearing, because the temperature range makes small affection on its precision.
