Stable SX Crossed Roller Bearings for Machine Tool Rotary Units

What are SX Crossed Roller Bearings?

SX crossed roller bearings are compact,high-precision locating bearings featuring cylindrical rollers arranged in an X-pattern (at 90-degree angles to each other) between an integral inner ring and a split outer ring.

Precision grades cover P5,P4 and ultra-precision P2.Metric series inner diameter ranges from 70 mm to 500 mm,outer diameter spans 90 mm to 620 mm and cross-section height varies between 10 mm and 56 mm.Precision machined shoulder structures come with standard positioning surfaces and built-in greasing holes for convenient lubrication maintenance.

Bearing rings and rolling elements can select GCr15 high carbon chromium steel or SUS440C stainless steel for corrosive surroundings.Cage choices include brass,reinforced Nylon 66 and custom high-load dedicated composite materials.Sealing solutions contain open type and contact rubber seals UU or U.Open version suits clean high-load medium-low speed working conditions requiring regular external lubrication.Contact rubber seals offer dustproof and splash-proof performance for complex heavy-load industrial environments.

Standard product delivery takes 7-15 working days.Customized items need further confirmation with the manufacturer.Available custom scope includes non-standard dimension,shoulder parameter modification,heavy-load optimization,corrosion resistant material upgrade and special lubrication for ultra-high or low temperature conditions.

The Features of SX Crossed Roller Bearings

Two-Piece Outer Ring/One-Piece Inner Ring:The outer ring is split circumferentially into two identical halves and secured with retaining rings,while the inner ring is a continuous,solid single piece.Optimized for high-precision inner-ring rotation.

90°Orthogonal Roller Arrangement:Cylindrical rollers alternate at right angles inside precision ground V-groove raceways.A single bearing handles radial loads,double-direction axial thrust,and heavy tilting moments simultaneously.

Full Complement or Plastic Spacer Options:Full Complement (XU/SX Series):Maximizes the number of rolling elements for extreme radial and moment load ratings.

Plastic Spacers:Prevents roller-to-roller contact and skewing,providing lower friction torque for high-speed applications.

High Rigidity in Narrow Cross-Sections:Roller line contact delivers up to 3 to 4 times the structural stiffness of ball bearings with identical dimensions.

Preloaded for Zero Backlash:Available in factory-preloaded or small-clearance classes to ensure zero axial/radial play,high tilting stiffness,and sub-micron rotational runout.
