NTN-SNR Linear Motion: Ball Bushings

As one of the leading manufacturers of rolling bearings in Europe, NTN-SNR has been, for many years, among the most innovative companies within its sector of industry. Since April of 2008, SNR has been a part of a corporate group together with the Japanese company NTN, making it the third largest manufacturer of rolling bearings in the world. Hence, we are able to offer “added value” to our customers with reference to product variety, quality and service. Our company is clearly identified through a worldwide presence and through its continous quality system. Since 1985, we are also active...

Standard ball bushings, closed The closed ball bushings of the BBE series according to ISO 10285 are widely utilized In various applications because of their precise cylindrical shape and good operational qualities. The standard ball bushings can be supplied from stock, with two wiper seals. The required seals are to be included when ordering. Optional relubricable Examples of order reference for a ball bushings with single-sided seal: BBE12U, BBE12AU Examples of order reference for a ball bushings with double-sided seal: BBE12UU, BBE12AUU Examples of order reference for a ball bushings...

The indicated load ratings are applicable in case the load only applies to one row of balls. If, however, the force is shared between two rows of balls, the load capacity is increased (refer to table on page 75).

Standard ball bushings, open Where bending (deflection) of the shaft has to be avoided, open standard ball bushings are utilized in combination with shaft supports. This is often the case for applications with extended travel. By way of the combination described above, the stiffness is in fact additionally increased. The standard ball bushings can be supplied from stock, with two wiper seals. The required seals are to be included when ordering. Optional relubricable Examples of order reference for a ball bushings with single-sided seal: BBE12U-OP, BBE12AU-OP Examples of order reference for...

The indicated load ratings for open ball bushings are only applicable where the load is applied from above; if the load is applied from the "open direction", the load capacity is reduced by the following factor (refer to table on page 75).

Standard ball bushings, adjustable The slotted standard ball bushings can be built Into a casing with an adjustable Internal diameter, allowing the clearance between the shaft and the ball bearing to be set. The standard ball bushings can be supplied from stock, with two wiper seals. The required seals are to be included when ordering. Optional relubricable Examples of order reference for a ball bushings with single-sided seal: BBE12U-AJ, BBE12AU-AJ Examples of order reference for a ball bushings with double-sided seal: BBE12UU-AJ, BBE12AUU-AJ Examples of order reference for a ball bushings...

The indicated load ratings are applicable in case the load only applies to one row of balls. If, however, the force is shared between two rows of balls, the load capacity is increased by the following factor (refer to table on page 75).

Standard flanged ball bushings (round) Flanged ball bushings of the BBER series represent a useful addition to the standard ball bushings. They offer the following advantages: •  he integrated flange design enables a more efficient arrangement of the housing or T mounting holes. •  he flanged ball bushings are economical, because fewer components are required and altogether the installation is easier. T •  he replacement of the ball bushings is easier. T The standard ball bushings can be supplied from stock, with two wiper seals. The required seals are to be included when ordering. Optional...

The indicated load ratings are applicable in cases where the load only applies to one row of balls. If, however, the force is shared between two rows of balls, the load capacity is increased by the following factor (refer to table on page 73).

Tandem standard ball bushings The tandem standard ball bushings of the BBE,,,L series have the same dimensions and tolerances of the ISO standard ball bushings, however they are twice as long and they are applied where high moment load exists. The big advantage of this type of ball bushings is that two standard ball bushings may be replaced. Since the concentricity is built in, increased accuracy is achieved and manufacturing costs reduced. The standard ball bushings can be supplied from stock, with two wiper seals. The required seals are to be included when ordering. Optional relubricable...

The indicated load ratings are only applicable in cases where the load is being applied to a single row of balls bearing. If, however, the force is shared between two rows of balls, the load capacity is increased by the following factor (refer to table on page 75).

Tandem flanged standard ball bushings (round) The ball bushings of the BBER…L series combine the advantages of flanged standard ball bushings with those of tandem ball bushings, since they provide a rigid, aligned linear guidance through their length, allowing the application of a second ball bearing. The standard ball bushings can be supplied from stock, with two wiper seals. The required seals are to be included when ordering. Optional relubricable Examples of order reference for a ball bushings with single-sided seal: BBER12LU, BBER12LAU Examples of order reference for a ball bushings...

The indicated load ratings are only applicable in cases where the load is being applied to a single row of balls. If, however, the force is shared between two rows of balls, the load capacity is increased by the following factor (refer to table on page 75).

Middle flanged standard ball bushings (round) Tandem ball bushings of the BBERM… series with a middle flange are designed specially for applications in which the shafts are perpendicular to the mounting surface. They remove the need for a housing and simplify the installation. Optional relubricable The standard ball bushings can be supplied from stock, with two wiper seals. The required seals are to be included when ordering. Examples of order reference for a ball bushings with single-sided seal: BBERM12U, BBERM12AU Examples of order reference for a ball bushings with double-sided seal:...
