ASAHI brand introduction

ASAHI Asahi Seiko Co., Ltd. was established in 1928 and initially only produced bearings. In 1951, it was the first Japanese manufacturer to start the production of multi-block bearings, and it is also the current professional manufacturer of external spherical bearings in Japan. Since then, as a pioneer, the company has been committed to the standardization and quality standard formulation of block bearings. After 1975, the company began to produce other new products, such as linear motion products. In the industry, ASAHI bearings have now become a trusted brand

ASAHI Asahi Seiko Co., Ltd., Japan's professional manufacturer of outer spherical bearings with seat. Convinced that professionalism is the best, we are committed to providing users with a complete range of products with high quality and low price.

So far, ASAHI produces 9 series of outer spherical bearings with seat. Including bearing housings, outer spherical bearings, joint bearings, rod end bearings, the main products are bearing housings. The outer spherical bearing housings are made of cast steel, cast iron, engineering plastics, stainless steel and steel stamped bearing housings. The inner hole of the bearing has two types: cylindrical and conical. The fixing methods to the shaft include the fixed type with top screw, the fixed type with eccentric sleeve, and the type with adapter sleeve.

ASAHI performance characteristics　　

1. Proper viscosity and good viscosity-temperature characteristics

In order to prevent the temperature of the main shaft of the machine tool from being too high to cause thermal deformation of the machine, affecting the machining accuracy or making the bearing poorly lubricated, lubricating oil with a suitable temperature should be selected according to the spindle bearing structure, speed and bearing clearance, etc., and it should have good viscosity-temperature characteristics. , To prevent the viscosity change from affecting the lubrication performance due to the large change of the spindle working temperature and ambient temperature.

2. Good lubricity

In order to maintain a uniform oil film between the contact surface of the main shaft and the bearing, and the oil film will not be damaged when the main shaft starts or stops moving and generates an impact load, maintaining good lubrication performance plays a role in reducing friction and frictional heat, reducing the temperature rise of the main shaft, and ensuring The function of machining accuracy requires good lubrication performance.

3. Good oxidation resistance

When the machine tool spindle adopts the circulating lubrication method, the spindle bearing oil is required to be used for a long time without deterioration, so it is required to have good oxidation resistance.

4. Good anti-rust performance

Since the oil will inevitably be mixed with condensed water in the air or machine tool coolant during the operation of the spindle lubrication system, the oil is required to have good rust resistance.
