UCT series with seat outer spherical bearing

Spherical ball bearings are a type of rolling bearing with an integral spherical outer ring, suitable for working conditions requiring high installation tolerance. They mainly consist of a spherical outer ring, rolling elements, inner ring and sealing structure, and most are used as complete sets with bearing housings (including pillow blocks, square flanged units, diamond flanged units, etc.). The spherical surface of the bearing outer ring matches the inner spherical surface of the housing to form an aligning structure, which can effectively compensate for shaft installation deviation, deflection deformation and misalignment. Featuring easy installation, strong adaptability and simple maintenance, they are standard general-purpose bearings widely applied in light industry, agricultural machinery, conveying, textile and other low-speed heavy-load scenarios. Our products fully comply with ISO international standards and can be used for equipment supporting and aftermarket replacement worldwide.

Product Features

1. Spherical self-aligning structure: The outer ring adopts a spherical design with excellent self-aligning performance, which can compensate for shaft misalignment, installation errors and shaft deformation, lowering requirements for installation precision.

2. Integrated sealing structure: Standard double-sided rubber seals and dust covers prevent dust, oil contamination and impurities from entering, making the bearings applicable to harsh environments with heavy dust, humidity and light grease pollution.

3. Easy installation and maintenance: The bearing can be directly fitted into the matched housing without complicated machining or precise positioning, enabling highly efficient disassembly, inspection and replacement.

4. Wide load adaptability: It can bear both radial loads and a small amount of bidirectional axial loads, performing stably under heavy-load and low-speed impact working conditions.

5. Compact and versatile structure: Featuring small overall dimensions and low installation space occupation, it comes with a full range of standard models and complete supporting bearing housing specifications for excellent interchangeability.

6. Reliable material and workmanship: Manufactured from high-carbon chromium bearing steel via precise heat treatment and precision grinding, it boasts high surface finish and smooth jitter-free rotation.

Product Advantages

1. Lower installation costs: The self-aligning property greatly relaxes precision requirements for shaft system installation, reduces equipment machining and assembly difficulty, and shortens the overall assembly cycle.

2. Excellent adaptability to harsh working conditions: Reliable sealing ensures stable operation in dusty, humid, vibrating and slightly oily environments to prevent premature failure.

3. High universal interchangeability: Manufactured in compliance with international dimensional standards, the bearings can directly replace similar products from mainstream brands in Europe, America, Japan and South Korea with no barriers for global equipment matching.

4. Extended service life: Premium bearing steel combined with mature heat treatment technology delivers outstanding wear resistance, fatigue resistance and vibration impact resistance, reducing frequent replacement costs.

5. Flexible complete-set supply: Bearings can be supplied separately or as complete assemblies with cast steel/cast iron bearing housings to streamline customers’ procurement and assembly processes.

6. Lower operation and maintenance costs: Designed for maintenance-free or minimal maintenance use, the sealing structure effectively blocks impurities, cuts lubrication consumption and failure risks for worry-free after-service management.

7. Wide range of application scenarios: Suitable for complex working conditions including low speed, medium load, vibration and limited installation space, far more versatile than ordinary deep groove ball bearings.

Main Application Fields

1. Agricultural Machinery: Tractors, harvesters, seeders, straw returners, agricultural conveyors, irrigation equipment.

2. Textile Equipment: Spinning machines, weaving looms, printing and dyeing machines, cloth winding machines, chemical fiber machinery and other textile transmission components.

3. Conveying Machinery: Belt conveyors, roller conveyors, bucket elevators, warehouse and logistics conveying lines.

4. Light Industrial Machinery: Food machinery, packaging machinery, printing machinery, woodworking machinery, fans, water pumps.

5. Mining and Building Materials: Crushers, vibrating screens, mixers, building material production equipment, auxiliary transmission equipment for mines.

6. Construction Machinery and Others: Small construction machinery, livestock breeding equipment, machine tool auxiliary devices, sports equipment, general transmission equipment.
