		Components	Parameters	Special Features	Applications
		Balls	Material	● Ceramic, Inox with hardened surface	● Hybrid bearings ● Higher limiting speed ● Uncertain lubrication
			Diameter	● Possible variation available: from 1/16² to 9/32² ● Limited by the minimum wall-thickness of the ring at the bottom of the raceway	● Modification of the limiting speed or the admissible load
			Number	● Possible variation limited by the mounting angle	● Increase of the admissible loads or shock resistance
			Number	● Full complement ball bearing, without cage	● Increase of the admissible load
			Surface Treatment	More information: Surface Treatment (Technical Information)	● Uncertain or dry lubrication
			Precision Class	● More or less precision compared to the standard WIB grade 5	● Less precision for cost reasons ● Higher precision as for the form tolerance
		Raceway	Surface Finish	● Rectified, unpolished	● Lower costs, low speed
			Surface Treatment	More information: Surface Treatment (Technical Information)
			Quantity	● 1 or 2	● Increase in the radial load capacity
			Angle of contact for 2 rows of balls	● Bigger	● Increase in the axial load capacity
			Form	● Deeper or less deep	● Variation of the radial clearance
			Form	● Wider or narrower or radius bigger or smaller	● Variation of the axial clearance ● Modification of the misalignment angle
			Position	● Off-centered	● Space for special seals ● Minimum width
