INDICATIVE DESCRIPTION

Single row angular contact ball bearing high precision 7914-CTR-SUMP3

These 7914-CTR-SUMP3 single row angular contact ball bearings high precision can accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They can operate at high speeds and, depending on the variant, even very high speeds.

They are more suitable than deep groove ball bearings for supporting large axial forces acting in one direction.

• High-speed capability
• Accommodate relatively high radial loads and large unilateral axial loads

High-precision bearings – Technical details by brand

The high-precision bearings offered by Texime are designed to deliver exceptional dimensional stability, smooth rotation, and extreme accuracy in the most demanding applications — such as machine tool spindles, high-speed motors, and measurement or automation systems.

Discover below the contact angles and cage types used by the main manufacturers.

1. Contact Angles

The contact angle determines a bearing’s ability to support axial loads and its maximum speed.
The smaller the angle, the higher the permissible rotational speed.
Each manufacturer uses its own designations.

FAG

• C = 15°
• D = 20°
• E = 25°
• B = 40°

For more information, please refer to the Schaeffler high-precision bearing catalog.

NSK (Series 70xx / 72xx / 79xx)

• C = 15°
• AS = 25°
• A = 30°

SKF

• CD = 15°
• AC = 25°
• F = 18°
• AB = 20° (for series 70 A and 719 A)

RHP

• E = 25°

SNFA

• 1 = CD = 15°
• 3 = AC = 25°

SNR/NTN

• C = 15°
• H, AD = 25°
• B = 40°

2. Cage Types

The cage retains the rolling elements and influences the bearing’s speed capacity, thermal resistance, and durability.
Each manufacturer uses its own cage designations.

FAG

• TVP = Plastic
• T = Laminated fabric

NSK

• TR = Phenolic resin
• MB = Brass cage
• TB = PPS

SKF

• For further details, please refer to the SKF high-precision bearing catalog.

RHP

• T = phenolic

SNFA

• C = Phenolic resin

SNR/NTN

• T1, G1 = phenolic
• T2 = polyamide
• V = laminated phenolic

Fafnir

• CR = phenolic
