Wuhan Ship Machinery passed the "dual system" audit

Recently, experts from the Certification Team of the Certification Center of the China Academy of Safety Science and Technology came to Wuhan Shipbuilding Co., Ltd. to conduct an occupational health and safety and environmental management system (hereinafter referred to as “dual system”) supervision and audit. During the audit, the audit team experts highly praised the company's "dual system" management work, and recommended that the company continue to maintain the certification registration qualification.

It is reported that through five days of on-site audit, communication, and inspection records, the audit team agreed that the company's "dual system" operation is effective, highlighting the four highlights of the company's "dual system" management: First, the company's "dual system" management achieved Good performance, no safety or environmental accidents occurred; Second, the company's leaders attach importance to the safety and environmental awareness of all employees; thirdly, the company always implements the "people-oriented" safety concept and strives to create a safety culture atmosphere. Fourth, the safety production party The government has the same responsibility, and has jointly managed to improve the management level of the company's "dual system."



Angular contact ball bearing can withstand both radial load and axial load. Able to work at a high speed. With larger contact angle, the axial capacity of the bearing will be higher. High precision and high speed bearings usually have a 15 degree contact angle. The contact Angle will increase under axial force.

Angular contact ball bearing accuracy class includes dimensional tolerance and rotation precision.The precision is expressed as P0(ordinary), P6(P6X), P5, P4 and P2.In addition, the European and American brands also use P3, P7 and P9 to indicate the accuracy level. P3 is the P6 level of ISO and JIS standard, P7 is equivalent to P4, P9 is equivalent to P2.


Single row angular contact ball bearings application are:machine tool spindle, high frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft, booster pump, drilling platform, food machinery, dividing head, filling machine, low noise type cooling tower, electrical equipment, coating equipment, machine tool trough plate, arc welding machine.
