Description
Product Overview
The Sealmaster NP-23T pillow block bearing is engineered for demanding industrial environments where reliability and durability are paramount. Constructed from a solid cast‑iron housing, the unit provides exceptional rigidity and resistance to wear, ensuring a stable platform for rotating shafts. The non‑expansion design incorporates a concentric locking collar that secures the bearing to the shaft without axial movement, eliminating the risk of misalignment during operation. Felt seals are integrated to protect internal components from dust, moisture, and other contaminants while retaining lubrication for extended service life. The bearing features a relubricatable steel ball assembly, allowing maintenance personnel to replenish grease without disassembly, reducing downtime and maintenance costs. With a 1‑7/16″ bore and a 1‑7/8″ base‑to‑center height, the NP‑23T fits a wide range of standard shaft sizes and mounting configurations, making it a versatile choice for many power transmission applications.
Usage
This pillow block bearing excels in applications such as conveyor systems, agricultural equipment, material handling machinery, and general industrial gear trains. Its robust construction tolerates both radial loads and combined radial‑thrust forces, making it suitable for high‑speed motors, gearboxes, and pump drives. The sealed design enables operation in dusty or humid environments, while the relubricatable feature allows for periodic greasing during routine maintenance cycles. Installation is straightforward: the two‑bolt housing aligns with a pre‑drilled mounting surface, and the shaft is inserted through the bore, where the locking collar clamps securely. The bearing’s dimensions and bolt‑hole spacing (5″ width) conform to common mounting standards, simplifying retrofits and new equipment builds. Operators benefit from reduced vibration, smoother operation, and extended bearing life, translating to lower total cost of ownership.

FAQ
What load capacities can the NP‑23T handle?
The NP‑23T is rated for moderate radial loads and combined radial‑thrust loads typical of industrial machinery. Exact capacity values are provided in the technical data sheet and depend on operating speed and lubrication conditions.
Can the bearing be re‑greased in the field?
Yes, the bearing features a relubricatable design. Grease can be injected through the access ports using standard bearing grease guns, allowing maintenance without removing the bearing from its mounting.
Is the bearing suitable for high‑temperature environments?
The cast‑iron housing and steel balls are rated for temperatures up to 200 °F (93 °C) when properly lubricated. For applications exceeding this range, a specialized high‑temperature bearing should be selected.
How do I install the locking collar correctly?
After inserting the shaft through the bore, rotate the locking collar until it seats firmly against the housing shoulder. Tighten the set screws to the specified torque to ensure a secure, non‑expanding fit.
What warranty does Regal provide?
Regal offers a one‑year limited warranty covering material defects and workmanship. Warranty terms are detailed in the accompanying documentation and can be extended through authorized service contracts.
