KFL004 Diamond-shaped Zinc Alloy Pillow Block Bearing

KFL004 Diamond-shaped Zinc Alloy Pillow Block Bearing

⚙️Structural and Material Characteristics:

Dual-material combination: This bearing adopts an integrated design of "bearing unit + zinc alloy housing". The bearing housing is formed by zinc alloy die-casting, which has excellent corrosion resistance and machining accuracy; the inner ring of the bearing is made of bearing steel, with high hardness and excellent wear resistance.

Installation positioning design: The extended end of the inner ring is equipped with two locking screws, which can be directly fastened and connected to the 20mm shaft diameter transmission shaft; the rhombic bearing housing reserves installation holes, supporting quick fixation and disassembly.

Self-compensation function: The rolling bearing unit can rotate slightly during installation, automatically compensating for the installation deviation of the shaft system, reducing running wear.

Long-life lubrication design: Before leaving the factory, it is filled with special lubricating grease, and under normal operating conditions, it can achieve "lifelong lubrication", eliminating the need for frequent maintenance.

⚙️Performance advantages:

Versatility: Compatible with various working conditions, it can replace models like KFL4UU and KVFL4LL of the same type in multiple scenarios such as HVAC systems and conveying equipment.

Durability: The zinc alloy base body is resistant to environmental corrosion, and the bearing steel inner ring has excellent fatigue resistance. After testing, it can withstand continuous high-frequency operation.

Economy: Compared to the stainless steel SKFL004 model, it offers lower costs while meeting general working conditions, and the weight is reduced by approximately 92%.

Low noise operation: The precisely processed raceways and optimized lubrication scheme can effectively reduce operating noise, making it suitable for equipment with high requirements for quietness.

⚙️Typical application scenarios:

Thanks to its lightweight, easy installation and high rotational speed features, KFL004 is widely used in the following fields:

Industrial equipment: conveyor drum, packaging machinery transmission mechanism, agricultural irrigation pump shaft system;

Consumer machinery: rotating components of fitness equipment, fan shaft of ventilation equipment, film transmission system of film production equipment;

DIY and small-scale equipment: main shaft of small motors, transmission shaft of experimental devices, rotating structure of household appliances.

⚙️Precautions:

1. Keep clean	2. Use with caution	3. appropriate tool	4. Hot-loading	5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.	Strong impact during use can easily cause scratches and indentations.	Avoid replacing existing tools, and use appropriate tools.	Bearings are precision parts, so hot installation is recommended.	Sweat on your hands during operation will cause rust, so it is best to wear gloves.
