607 Deep Groove Ball Bearing 7x19x6mm
The 607 bearing occupies the 7mm bore position in the 600 series: a standard ISO size with 19mm OD and 6mm width. It is the bearing that fits when a 608 bearing (8mm bore) is one millimeter too large on the shaft and a 606 bearing (6mm bore) is one millimeter too small.
Key Specifications
- Sealing: Open, ZZ (metal shields), or 2RS (rubber seals). ZZ reaches full speed rating with non-contact protection.
- Speed and Load: 40,000 RPM (open) with 2.34 kN dynamic and 0.95 kN static load. 2RS configuration rated to 32,000 RPM.
- Radial Fit: 7mm bore, 19mm OD, 6mm width. 6mm radial cross-section; sits between the 606 bearing (6mm bore) and 608 bearing (8mm bore) in the narrow 600 series.
- Temperature Range: -20C to 120C with standard polyurea grease. 150C peak available with high-temperature lubricant on request.
- Precision: Standard ABEC-1. ABEC-3 and ABEC-5 available for tighter bore and radial runout tolerances.

Shielding and Lubrication
The 607 bearing ships in three sealing configurations. Open (no suffix) fits oil-bath and oil-mist lubricated housings where the lubrication system handles contamination control. ZZ shields use non-contact pressed-steel covers retained in the outer ring; they trap factory grease while adding zero friction, reaching the full 40,000 RPM rating. 2RS seals use nitrile rubber lips contacting the inner ring groove, blocking moisture and particulates at a reduced speed ceiling of approximately 32,000 RPM. The 2RS version ships pre-packed with polyurea grease and needs no field relubrication.
At 6mm width and 19mm OD, the 607 bearing has a compact cross-section where 2RS seal drag at 32,000 RPM can account for 8 to 10 percent of drive torque in low-power applications. ZZ shields avoid this entirely. For sealed gearmotors and enclosed drives, 2RS adds a layer of protection against grease migration from adjacent components. For open-frame motors in clean environments, ZZ is the lower-drag option.
Performance
The 607 bearing carries 2.34 kN dynamic and 0.95 kN static load at 40,000 RPM in open configuration. Within the narrow 600 series, the 606 bearing (6x17x6mm, 2.19 kN dynamic) gives up 0.15 kN of capacity for 1mm less bore. The 608 bearing (8x22x7mm, 2.89 kN dynamic) gains 0.55 kN for 1mm more bore and 3mm more OD. The 607 bearing weighs approximately 8g per unit.
The step to the 627 bearing (7x22x7mm, 3.35 kN dynamic) adds 3mm OD and 1mm width for a 43 percent load increase. If the housing can accept a 22mm OD, the 627 bearing delivers more capacity at the same 7mm bore. If 19mm OD is the housing limit, the 607 bearing is the standard bearing that fits without a housing redesign. For OEM deep groove ball bearing selection, bore and OD constraints define the series choice.
OEM and Customization
Yuanhe manufactures the 607 bearing to customer specifications beyond catalog dimensions. Common OEM requests for the 7mm-bore series include C2 or C3 radial clearance for precision spindle and motor applications, low-noise grease fills for medical and laboratory equipment, and 440C stainless steel rings and balls for autoclave and washdown environments. Non-standard bore tolerances and custom cage materials are available against drawing. For OEM orders, send bearing dimensions or part number for a quote.
Applications
Small DC motor armatures
Laboratory centrifuge spindles
Dental drill handpieces
Medical infusion pump drives
RC model motors and servos
Optical encoder shafts
Miniature gearbox input shafts
Precision measuring instrument spindles
Frequently Asked Questions
What is the difference between 607 bearing, 606 bearing, and 608 bearing? +
The 606 bearing has a 6mm bore and 17mm OD with 2.19 kN dynamic load. The 607 bearing uses a 7mm bore and 19mm OD with 2.34 kN dynamic load. The 608 bearing has an 8mm bore and 22mm OD with 2.89 kN dynamic load. Each step up adds 1mm bore and roughly 2-3mm OD. Specify the bearing that matches the shaft size: 606 bearing for 6mm, 607 bearing for 7mm, 608 bearing for 8mm shafts.
Can the 607 bearing run at 40,000 RPM continuously? +
In open configuration with oil-mist lubrication, yes. The 40,000 RPM rating applies to open bearings with adequate lubrication. ZZ shielded bearings also reach 40,000 RPM since the shields are non-contact. 2RS sealed bearings are rated to 32,000 RPM due to seal lip friction heating. For continuous operation near the speed limit, verify that the bearing operating temperature stays below the grease rating.
What shaft and housing tolerances should I use with a 607 bearing? +
For standard electric motor applications with a rotating shaft and stationary housing: shaft tolerance j5 or j6 for the inner ring fit; housing tolerance H7 for the outer ring fit. For press-fit conditions or elevated temperatures, select C3 internal clearance to compensate for thermal expansion. Contact Yuanhe with your specific housing material and temperature range for a tolerance recommendation.
Is the 607 bearing available in stainless steel for medical device applications? +
Yes. Yuanhe manufactures the 607 bearing in 440C stainless steel for medical devices, laboratory equipment, and food processing machinery. Stainless steel reduces the dynamic load rating to approximately 1.87 kN and the maximum speed to 28,000 RPM due to lower hardness compared to GCr15. Full ceramic (Si3N4 rings and balls) is also available for non-magnetic and non-lubricated applications. Specify material at the RFQ stage.
