Combined Needle Roller / Thrust Ball Bearing NXRT9020DDCOPS for Industrial Robot

Crossed Roller Bearing NXRT9020DDCOPS Sealed High Precision 90×140×20mm for Industrial Robot & Rotary Table

The NXRT9020DDCOPS Combined Needle Roller and Thrust Ball Bearing is engineered for compact machinery requiring heavy radial load capacity alongside dual-direction axial support. It is widely used in automation equipment, machine tools, and industrial drives where mounting space is strictly constrained.

• Model: NXRT9020DDCOPS (Series: NXRT / Combined Needle Roller Bearing)

• Inner Diameter (ID): 20 mm

• Outer Diameter (OD): 35 mm

• Total Width / Height: 28 mm

• Structure: Radial Needle Roller Bearing + Dual-Direction Thrust Ball Bearing Assembly

• Material: Premium Chrome Steel (GCr15 / 100Cr6)

• Sealing Type: DD (Rubber Seals on Both Sides)

• Precision Rating: P0 / P6 (ABEC-1 / ABEC-3)

• Dual-Direction Axial & Heavy Radial Load Support: Combines a radial needle roller set with a thrust ball assembly for comprehensive multi-directional load handling.

• Integrated Rubber Sealing (DD): Equipped with double-sided rubber contact seals to prevent lubricant leakage and block dust and contaminants.

• Ultra-Compact Cross Section: Saves significant radial and axial envelope space compared to using separate radial and thrust bearings.

• High Precision & Operational Rigidity: Precision-machined outer ring and rollers ensure minimum shaft deflection and smooth, low-vibration operation.

• Raw material composition, purity, and microstructural analysis.

• High-precision CNC machining, super-finishing, and automated raceway grinding.

• Controlled heat treatment for optimal surface hardness and fatigue strength.

• 100% Dimensional accuracy, internal clearance, and rotational noise testing.

• Protective anti-rust treatment and individual sealed packaging before dispatch..

• Q1: Can you provide custom crossed roller bearings or OEM branding?Yes, we support OEM laser marking, custom packaging, and non-standard tolerances, preload levels, or mounting holes based on your drawings.
• Q2: What do the suffixes "DD", "C0", and "P5" mean in NXRT9020DDCOPS?"DD" indicates double-sided contact rubber seals, "C0" specifies normal radial/axial preload for zero clearance, and "P5" denotes ISO Class 5 high rotational precision.
• Q3: Does the outer ring of NXRT9020DDCOPS rotate or stay stationary?Because the outer ring is split into two halves held together by rivets/bolts, this model is designed primarily for inner-ring rotation applications.
• Q4: What quality certifications does your factory hold?Our manufacturing facility operates under strict ISO 9001 quality management standards, with full accuracy and material inspection reports provided with every shipment.
• Q5: What is your delivery time and shipping method?Standard precision models ship within 7–15 days, while custom orders depend on specifications. We support sea freight, air freight, and express courier (DHL/FedEx/UPS) worldwide.
