SS UCP209 Stainless Steel Pillow Block Bearing Unit 45mm Bore Anti-Corrosion Set Screw Lock

1. Product Overview

SS UCP209 is fully anti-corrosion two-bolt vertical pillow block bearing unit, composed of stainless steel SUC209 spherical insert bearing and stainless steel SP209 pedestal housing, standard 45mm shaft bore.

Prefix & Suffix Code Explanation:

• SS: Entire unit adopts AISI304 stainless steel material, including housing, inner/outer ring, steel ball and sealing shell, excellent resistance to water splash, humidity and weak acid corrosion
• UC: Insert bearing with double extended inner ring, equipped with two hex socket set screws for reliable shaft locking
• P: Two-bolt vertical pillow block housing, stable pedestal structure for horizontal base mounting
• 209: Nominal shaft bore size 45mm, matched with standard 45mm solid transmission shaft

The spherical outer surface of the insert bearing fits the inner spherical bore of the pedestal housing, providing ±2° self-aligning capacity to compensate shaft installation misalignment and equipment thermal deformation offset. Double-layer stainless steel reinforced contact seal blocks moisture, food residues and workshop dust. Built-in stainless steel grease nipple supports regular supplementary lubrication. Widely used in food processing production lines, beverage filling equipment, marine fishing machinery, aquaculture conveying equipment, light chemical processing equipment and all humid, corrosive working environments.

2. Technical Specifications

Mounting dimension drawings, food-grade lubrication installation guides and salt spray anti-corrosion test reports can be provided on customer request.

3. Core Advantages

1. Full AISI304 stainless steel integrated structure, effectively avoid rust and oxidation under long-term humid, water splash and weak acid working conditions, perfectly match food, marine and aquaculture anti-corrosion application scenarios.
2. Thickened stainless steel two-bolt pedestal housing, high rigidity stable base structure, uniform load distribution, strong anti-vibration performance during continuous heavy-load operation.
3. Spherical self-aligning insert bearing design, automatically eliminate parallel and angular offset between shaft and mounting base, reduce abnormal wear caused by assembly error and equipment thermal expansion.
4. Double M8 set screw locking on double extended inner ring, uniform clamping force on shaft surface, anti-slip under continuous vibration and humid environment, prevent inner ring creep and shaft surface scratch.
5. Double-sided composite stainless steel contact seal, dual barrier protection, isolate clean water, organic residues, workshop dust and light chemical mist to prevent internal raceway abrasion.
6. Reserved stainless steel grease nipple for periodic relubrication, extend service life of bearing unit under long-time unattended production line operation.
7. Standard metric interchangeable overall dimension, fully compatible with global SS UCP209 stainless steel pillow block bearing units, direct replacement without modifying equipment base structure.
8. Rich customizable options: Food-grade stainless steel raw material upgrade, food-safe white grease pre-filling, enhanced multi-layer waterproof sealing, OEM laser marking on housing surface, neutral export anti-rust carton packaging.
