J Series Thrust Bearings

J series thrust bearings are designed and manufactured to allow equipment manufacturers and operators a high quality bearing assembly that is interchangeable with other bearing manufacturer’s designs. They are an equalising type design with six thrust pads which have hardened spherical centre located pivots; this allows operation in both directions of rotation. They can be supplied as a single or double thrust assembly and if required with a standard thrust collar. Machining or complete installation can be provided for thermocouples, RTD sensors and load cells. All assemblies are available in carbon steel, bronze, copper-chrome zirconium alloy backing material. Our most common products are shown below but we can supply thrust bearings in any size required.
