Pump Bearings
-- Steady & Reliable Manufacturer --
Brief Description
Precision bearings, often Angular Contact Ball Bearings (ACBB), optimized to manage both the high radial loads of the impeller and the critical thrust loads generated by fluid movement in industrial pumps.
Introduction
Bearings in fluid pumps (centrifugal, vertical, and chemical) face unique challenges, primarily handling the high axial (thrust) load caused by the fluid impeller and maintaining rotational stability near high moisture/corrosion sources. We supply high-precision, typically P5 or P6 grade, ACBBs often supplied in duplex (paired) arrangements to precisely handle the thrust forces in two directions. Our focus on superior sealing and corrosion-resistant materials ensures maximum mean time between failures (MTBF), which is critical for continuous process industries like oil & gas, water treatment, and chemical processing.

Applications
-
Water Treatment: Centrifugal pumps and booster pumps.
-
Oil & Gas: High-pressure process pumps and submersible pumps.
-
Chemical Industry: Pumps handling aggressive or corrosive fluids (requires stainless steel or ceramic).
-
HVAC Systems: Circulation pumps and cooling tower systems.
Key Advantages
-
Superior Thrust Control: Precision-matched duplex sets handle high thrust loads more effectively than standard bearings, preventing shaft walk.
-
Extended Seal Life: High bearing precision ensures stable shaft running, maximizing the effectiveness of external shaft seals (mechanical seals).
-
Corrosion Resilience: We offer material options suitable for high-humidity or direct fluid contact environments.
-
Low Vibration: High precision translates directly into quieter, more stable pump operation and longer seal life.
