摘要： PROBLEM TO BE SOLVED: To provide a bearing seal material having a pollution-less protective film in place of a harmful chromate treatment. SOLUTION: In a metallic seal material 2 to be used for at least a part of a bearing seal or a shield member (hereinafter, referred to as the bearing seal material), a surface of a steel sheet of 0.1-0.5 mm in thickness is covered with a film 2a consisting of a more precious metal than iron and of 0.5-50 μm in thickness. In the shield 2, a corrosion resistant film 2a which consists of a metal smaller in ionization tendency than iron and requires no chromate treatment, and does not adversely affect the environment is formed as a protective film on the surface 1a of the base steel sheet 1. A specific example of the corrosion resistant metallic film 2a includes a tin or copper coating.

摘要： PROBLEM TO BE SOLVED: To provide a hydrostatic air bearing type straight advance guide improving bearing performance and lowering manufacturing costs, etc. SOLUTION: This hydrostatic air bearing 3 is constituted by two identical bearing blocks 5 having a nearly L-shape section. Pairs of bearing pad loading concavities 5a, 5b facing to a slider axis 1 are formed at right angles to each other, in the bearing blocks 5. An air communicating hole 23 is formed in the bearing blocks 5 in order to communicate respective compressed air supplying ports with the respective bearing pad loading concavities 5a, 5b. Bearing pads 21 forming diaphragm parts are fitted into the respective bearing pad loading concavities 5a, 5b in the axial same positions. The bearing pads 21 are supplied with compressed air from a compressed air supplying tube through the air communicating hole 23. The prescribed clearances are formed between the slider axis 1 and the respective bearing pads 21 by the compressed air blowing out from the respective bearing pads 21, to float and support the slider axis 1 in the center of the hydrostatic air bearing 3.

摘要： PROBLEM TO BE SOLVED: To provide a lubricating device for a ball screw to perform sufficient lubrication in high load application. SOLUTION: Since a lubricant-containing polymer member 20 making slide contact with only the outside diameter part of a screw shaft 1 is mounted on a ball nut 2, scraping-down of a lubricant adhered to a screw groove 1b during reciprocating operation of the screw shaft 1 is prevented from occurring by the lubricant-containing polymer member 20. This constitution effectively holds the lubricant adhered to the screw groove 1b.

摘要： PROBLEM TO BE SOLVED: To provide the holder for a ball bearing which can manufacture more easily regardless of preventing a jitter. SOLUTION: As the claw part 4a is deformed based on the rotation of a bearing and thereby one part of the claw 4a is contacted to the outer periphery surface of the ball 3, in a manufacturing process, a gap is formed between the ball 3 and claw part 4a and thereby, a cleaning becomes easy. While, at the action time of the ball bearing, as one of the claw part 4a is contacted to the outer periphery surface of the ball 3, a grease or the like adhered on the ball 3 can always be raked off and thereby, a jitter can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a bearing rigidity evaluating apparatus capable of accurately obtaining a bearing rigidity for a bearing to which a pre-load is given.
SOLUTION: In the bearing rigidity evaluating apparatus, a vibration is excited at a bearing 4 by an exciter 1, and the vibration excited at the bearing 4 is detected by vibration detecting sensors 21a, 21b, and 21c. Output signals of the sensors 21a, 21b and 21c for an outer rece 42 of the bearing 4 are added in a time series by an adder 23, then input to a transfer function calculator 3a, and the signal of the sensor 21a is input to the calculator 3a. The calculator 3a calculates a transfer function H between an inner face and the outer race (between a hub shaft 41 and the race 42), and obtains a vibration mode in which a resonance frequency (intrinsic frequency) fa is present in the relation of a different phase of-π/2 caused by erasing a vibration component (the same phase component) of a local mode contained in the input signals from the function H.

摘要： PROBLEM TO BE SOLVED: To reduce rotational non-synchronous components of both axial run-out and radial run-out by combining rolling bearings setting the number of rolling bodies to be a prime number over a specific number with rolling bearings setting the number of rolling bodies to be the number having divisors over a specific pieces. SOLUTION: In a bearing spindle using rolling bearings in a plurality of rows, rolling bearings 10 setting the number of rolling bodies to be the number having divisors over three and rolling bearings 20 setting the number of rolling bodies to be prime number over eleven are combined together to be used. Because the main component of shape error of the raceway surface of inner/oute rings is under the control of low frequency component up to ten crests, by setting the number of rolling bodies to be the prime number over eleven, rotational non-synchronous run-out can be reduced. Further, the main low frequency crest component of the raceway surface shape error to 2-10 crests is a main body, and hence by setting the number having divisors up to 2-10 over three pieces to be the number of rolling bodies, the rotational non-synchronous component of radial run-out can be reduced.
