PROBLEM TO BE SOLVED: To provide a nonseparable angular contact ball bearing which is low in heating temperature during assembling, is easy in operation, causes no damage of a ball during assembling, keeps the outer ring or the inner ring not separated during handling, and also is long in bearing life during use. SOLUTION: The nonseparable angular contact ball bearing 1 comprises suitably setting an upper and a lower limit values of a hanging allowance in response to a radius of a circumscribed circle in which a ball is arranged when the ball 4 is moved to the inner ring 3 or a maximum radius of a truck surface of the outer ring 2, (heating temperature of outer ring-room temperature during assembling), a coefficient of thermal expansion of a material of the outer ring, and a clearance inside a radial.
