BALL BEARINGSThe basic bearing of excellence, the ball bearing is designed to accept radial and/or axial loads according to internal design Possible cage variants (suffixes)

EMTR range: low noise quality level with optimised design especially for electrical motors MEGAOHM range: bearings with electrical insulation, mainly for applications with electrical motors and generators CLEAN range: for environments with an extreme vacuum (semi-conductors, aeronautics, etc.) Bearings with integrated sensors (pg.16) Bearings with solid lubrication (pg.15) ANGULAR CONTACT BEARINGS High precision range (see pg. 12) STANDARD range depending on series and dimensions, angle of 30°: 1 row: 7800, 7900, 71900, 7000, 7200, 7300, 7400 Large bearings: bore < 1060 mm. 2 rows: 5200, 5300,...

TAPERED ROLLER BEARINGS These accept high radial loads and axial loads in one direction. ­ They are generally fitted opposite a bearing of the same type. Load capacity depends on contact angle. TAPERED ROLLER BEARINGS 1 ROW Metric dimensions: ISO 355 and JIS B 1512 standards Available with contact angles, spread from 10° to 31° including 2 series of large contact angle (T7FC and 303xx D) Inch dimensions: ABMA standard (including J metric series) Can be equipped with flanges TAPERED ROLLER BEARINGS 2 ROWS Appears in the same form as two single-row bearings Fitted face-to-face or back-to-back,...

This unit compensates for shaft bending and absorbs misalignment defects. These accept high radial loads and axial loads in both directions. Available with tapered or cylindrical bores. Tapered bores are delivered with adapter or withdrawal sleeves. NTN-SNR HIGH PERFORMANCE RANGE: - Series: 21300 / 22200 - 22300 / 23000 - 23100 - 23200 - 23800 - 23900 / 24000 - 24100 - 24800 - 24900 - High performance standard. Optimal quality steel, geometry and optimised surface conditions, maximum dynamic load capacity service life of the bearings (X2). - Increased speed limits - Reduced energy consumption -...

CYLINDRICAL ROLLER BEARINGS These bearings are highly rigid and can absorb high radial forces. Cage versions accept higher speeds than full complement versions. Equipped with separable rings, dismounting and withdrawal are simple, even when tight clearances are necessary. Standard range ISO standard: NU, N, NJ, NF, NUP, NH, RNU, HJ Series of bearings: 200, 300, 400, 1800, 1900, 1000, 2900, 2200, 2300, 3800, 3100, 3200, 3300 US types (BOWER): M, W Possible variants • Tapered bore (K) • Grooves with (NR) or without a snap ring (N) on the outer diameter to simplify assembly • Fully case hardened...

2 ROWS CYLINDRICAL BEARINGS WITH CAGE Standard range: NN and NNU with solid cage Series: 3900, 3000, 3100, 4800, 4900, 4000 Type NN and NNU bearings: also available with a tapered bore Types of applications: machine tools (see § High Precision pg.12) or heavy industry 4 ROWS CYLINDRICAL BEARINGS WITH CAGE (TYPE 4R) Bearings with solid cage, also available in large dimensions (d. < 1200 mm) Possible variants • Case hardened or carbo-nitrided steel for improved resistance • Lubrication holes 2 ROWS CYLINDRICAL FULL COMPLEMENT (TYPE SL) Range suitable for high radial loads and/or to meet the need...

These bearings are mainly selected for constructions requiring reduced radial dimensions and maximum rigidity and load capacity. They have little resistance for axial forces (except thrusts and combined bearings). NEEDLE ROLLER AND CAGE ASSEMBLIES A needle cage comprises an inseparable cage and needles and can be used to design very compact, light, constructions with maximum capacity. The shaft and housing act as a raceway and must be machined in compliance with hardness, geometry and roughness characteristics. The needles are guided precisely, therefore the needle cage can absorb much higher...

These solid rings and needle bearings are also available in inch dimensions. (MR,MI) NEEDLE AND ROLLER THRUST BEARINGS Needle or roller thrust bearings are designed to absorb axial forces in one direction only. Support surfaces used as raceways must be ground and hardened. • Needle thrust bearings: type AXK11 • Roller thrust bearings: series 811, 812, 874 and 893 Available with Polyamide cage (-T2), Aluminium alloy cage (-: lightness and enhanced performance when lack of lubricant) or pressed steel cage. • Washers: - type AS11 washers are thin (1 mm), therefore their support surfaces must be...

HIGH PRECISION BEARINGS These bearings are mainly selected for constructions requiring reduced radial dimensions and maximum rigidity and load capacity. They have little resistance for axial forces (except thrusts and combined bearings). MACHLINE BY SNR • High precision MACHLINE: Standard 71900V and 7000V series: An ideal compromise between performances in terms of speed, rigidity, capacity and precision 7200G1 series: - Specially designed for applications with predominantly high axial loads. - Variants depending on contact angle: C for 15°, H for 25° - Variants depending on preload: light, medium,...
