摘要： A spacer manufacturing method can manufacture a spacer to be mounted in a spindle stock, so precisely and simply at a low cost as need not use a bearing of a large size or a bearing of a special design so as to support an unclamping force. An inner-ring spacer (4) and an outer-ring spacer (5) have load receiving portions (4a and 5c), which confront each other in the axial direction through a clearance (d) of a predetermined size, and are halved in splitting planes (F1 and F2) normal to the axial direction and extending through the load receiving portions (4a and 5c). An inner-ring spacer splitting member (4A) having a load receiving portion (4b) and an outer-ring spacer splitting member (5A) having the load receiving portion (5c) are simultaneously worked to have equal axial widths. In addition, an inner-ring spacer splitting member (4B) not having the load receiving portion (4b) and an outer-ring spacer splitting member (5B) not having the load receiving portion (5c) are simultaneously worked to have equal axial widths, so that the axial width (b) of the latter may be longer by the clearance (d) than the axial width (a) of the former.

摘要： A bearing assembly includes a double-row cylindrical roller bearing having no seals and having a grease sealed in its internal space. A double-row angular ball bearing having seals is provided in juxtaposition with one end face of the double-row cylindrical roller bearing. During run-in, part of the grease sealed in the double-row cylindrical roller bearing adheres to the outer surface of one of the seals of the angular ball bearing that faces the internal space of the cylindrical roller bearing. This increases the initial amount of grease sealed in the internal space of the cylindrical roller bearing, thereby prolonging its life.

摘要： There is disclosed a cylindrical roller bearing (14) comprising an inner ring (1) having a raceway (1a) on an outer periphery thereof, an outer ring (2) having a raceway (2a) on an inner periphery thereof, and a plurality of cylindrical rollers (3) rotatably arranged between the raceway (1a) of the inner ring (1) and the raceway (2a) of the outer ring (2). At least one of the inner ring (1) and the outer ring (2) is provided with collars (1b) respectively on both sides of its raceway (1a), and at least one of the collars (1b) being provided with a recess (1c) at a corner where the raceway (1) intersects a collar surface (1b1). A critical skew angle &thetas;T, that is a maximum skew angle at which a boundary between an end face and a chamfer of the cylindrical roller (3) makes contact with a boundary between the collar surface (1b1) and the recess (1c), is restricted to be a predetermined angle or smaller. Contact surface pressure P increases rather drastically in proportion to skew angle &thetas; within the range of 0

摘要： To provide a rolling bearing assembly, in which a grease filled within the bearing assembly is utilized to achieve a high speed feature, a long life and a maintenance-free and a lubricant oil can be stably supplied from a minute gap, a stepped face continued from the raceway surface is provided in a stationary raceway ring unit of an inner and outer ring units in a direction away from rolling elements. A gap forming piece having a free end confronting the stepped face is provided to define therebetween a flow passage and a grease reservoir communicated with the flow passage. The rolling bearing assembly is so designed that a heat cycle can be induced in the grease reservoir and, base oil of the grease can be urged to flow out from the gap by the effect of a pressure variation caused by the temperature rise.

摘要： The object is to reduce the temperature rise and thermal expansion of the angular ball bearing by releasing heat produced therein to the housing, while keeping its outer race loosely fitted in the housing. By filling the gap between outer races 2a of combined angular ball bearings 2, which are loosely fitted in a housing 12, and the radially inner surface of the housing 12 with a heat conductive grease 3 containing inorganic powder as a heat conductive material, heat produced in the combined angular ball bearings 2 can be released from the outer races 2a to the housing 12 through the heat conductive grease 3. Thus, it is possible to reduce temperature rise and thermal expansion of the angular ball bearings 2, while keeping them loosely fitted in the housing.

摘要： A bearing performance automatic calculation service device is provided which allows a user to receive an automatic calculation service at any time in any location, which easily ensures reliability in terms of leakage of transmitted/received data, and which is easily used in terms of an input operation. An e-mail address is assigned, which is used only for receiving a request for an automatic calculation service. It is determined whether authentication information and a description content of a file 5 attached to an e-mail 4 satisfy a condition. Evaluation of performance of a bearing with respect to a determined evaluation item by means of a calculation formula on the basis of the file is performed. A result of the evaluation to the file 5 is added to create a sending file. The sending file 5 is attached and sent back by the e-mail sending module 17.
