Why Choose Oilless Bearings

Reduce Manufacturing costs

There is no need for oil supply device, oil injection hole or oil groove processing, which can greatly save manufacturing costs.

Reduce Operating Costs

It greatly reduces the usage of lubricating oil, reduces equipment maintenance, and avoids hidden dangers caused by insufficient oil supply, effectively reducing operating costs.

Shorten Design Time

The oil-free design simplifies the product structure and effectively saves design time. We are professional ODM Suppliers of MJGB Oil-free Injection Guide Bushing Standard Spare Part

Conducive To Environmental Protection

No waste oil recycling is required, which is also beneficial to environmental protection.

What types of testing are performed to verify the performance of Oil-free Injection Guide Bushing Standard Spare Part?

To confirm the overall performance of an oil-loose injection manual bushing standard spare element, several types of checking out may be completed. These tests are crucial to make sure that the bushing meets the specified specs and plays optimally. Below are some not unusual forms of trying out that may be conducted:

Dimensional Testing: This involves checking the size of the guide bushing to make certain it conforms to the specified specs. Measurements along with outer diameter, internal diameter, duration, and tolerance tiers are evaluated the usage of precision size equipment.

Material Analysis: This testing evaluates the material composition and residences of the manual bushing. It includes strategies which include chemical analysis, microstructural evaluation, hardness testing, and mechanical testing. Material analysis ensures the bushing is manufactured from tremendous, durable material with suitable hardness and power for its intended software.

Performance Testing: This type of checking out involves subjecting the guide bushing to real-international operating conditions to assess its overall performance competencies. The bushing is tested for elements like load capacity, put on resistance, friction coefficient, and heat dissipation. Performance trying out can be performed using specifically designed test rigs or by means of installing the bushing in an real working surroundings.

Lubrication Testing: Since the guide bushing is oil-loose, it's miles essential to confirm its performance with out the need for lubrication. This testing evaluates the friction traits and put on resistance of the bushing in the absence of any lubricant. It guarantees that the bushing can perform correctly without compromising its overall performance or requiring ordinary oiling.

Environmental Testing: The manual bushing may be subjected to various environmental conditions for the duration of its operation. Environmental checking out involves exposing the bushing to extreme temperatures, humidity, dust, and different environmental factors to evaluate its overall performance and durability underneath those conditions. It helps ensure that the bushing can resist harsh environments without degradation.

Compatibility Testing: The compatibility of the manual bushing with other additives and substances is crucial for its proper functioning. Compatibility checking out entails checking elements such as dimensional compatibility, chemical compatibility, and thermal compatibility. This guarantees that the bushing may be without difficulty established, works efficiently with different components, and forestalls any unfavorable reactions or failures.
