Nitrile rubber single lip contact seals help retain lubricant and prevent contamination
Concentric locking collar for 360-degree holding power on the shaft
303 stainless steel grease fitting on the housing for reapplying lubricant
This Sealmaster NP Series corrosion-resistant CR Duty pillow block ball bearing unit with a 316 stainless steel housing, lip seals, and a concentric locking collar is designed to support shafts operating in moist, corrosive, and abrasive environments. The cast-passivated 316 stainless steel pillow block housing provides resistance to corrosion and has a smooth finish that helps prevent debris from adhering to the unit. A locking pin-and-dimple system beneath the 303 stainless steel grease fitting feeds lubricant through the bearing, helps prevent outer-ring rotation within the housing, and allows for +/-2 degrees misalignment. The self-aligning deep-groove ball bearing insert in the housing supports radial and thrust loads and is made of vacuum degassed 52100 chrome steel for durability and resistance to deformity. A nylon-coated land-riding retainer spaces the ball rollers for even load distribution and prevents contact to reduce friction, vibration, and noise. The wide inner and outer races are coated with black oxide for corrosion resistance. Nitrile rubber single-lip contact seals on both sides of the bearing help retain H-1 food-grade grease applied at manufacture and prevent contaminants from entering the bearing. The bearing locks onto the shaft with a fluoropolymer-coated concentric locking clamp collar (Skwezloc) and two Torx head cap screws for 360-degree holding power. This lock type reduces vibration, helps protect the shaft from deep scoring, and is suitable for high-speed applications where the shaft rotates in a single or reversing direction. Operating temperatures for this bearing range from -20 to +220 degrees F. This pillow block unit is suitable for industrial and commercial applications including food and beverage processing plants, pulp and paper mills, and marine and naval applications, among others.
Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.
