6307DDU 6307-2RS NR C3 With Snap/Retaining Ring Deep groove Ball Bearings 6307NR-2RS 35x80x21 mm

Description 1.Deep Groove Ball Bearing Information: Single row radial ball bearings are the most widely used bearings and utilize an uninterrupted raceway, which makes these bearings suitable for radial loads, or a combination of thrust and radial loads. This design permits precision tolerances even at high speed operation. Shielded bearings are protected on one, or both sides (suffixes Z and ZZ, respectively) by metal shields fastened to the outer ring. This close clearance labyrinth seal retains the lubricant and prevents the entrance of foreign matter. Sealed bearings incorporate steel reinforced rubber seals securely fastened to a groove on the outer ring. Contact with the inner ring is by sealing lip (Contact Suffix LLU). Or, non-contact with the inner ring is by labyrinth seal (Non-contact Suffix LLB) to provide positive sealing at all times. 2.Deep Groove Ball Bearing Features: 1:Retainer: Brass/Nylon/Steel as your requirement 2:Single direction 3:Restricted tolerances 4:Vibration resistance 5:Suitable for high speed 6:Radial load Product  3.Deep Groove Ball Bearing Protection: 1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation. 2. Don’t allow strong impact, such as hammer striking, transfer roller pressure 3. Use the accurate installation tool, avoid to use cloth kind and short fibers 4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer 5. General inspection, such as the surrounding temperature, vibrate, noise inspection 6. Keep bearing cleaning from dirt, dust, pollutant, moisture. 7. Bearing should not be ultra cool Bearing No. I.D O.D W Loading Rating(KN) Steel Ball Parameter d D B Dynamic Static No. Size mm inch mm inch mm inch Cr Cor mm 6300 10 0.3937 35 1.3780 11 0.4331 8.20 3.50 6 7.144 6301 12 0.4724 37 1.4567 12 0.4724 9.70 4.20 6 7.938 6302 15 0.5906 42 1.6535 13 0.5118 7.75 5.45 7 7.938 6303 17 0.6693 47 1.8504 14 0.5512 11.40 6.55 7 8.731 6304 20 0.7874 52 2.0472 15 0.5906 13.50 7.90 7 9.525 6305 25 0.9843 62 2.4409 17 0.6693 15.90 10.90 7 11.500 6306 30 1.1811 72 2.8346 19 0.7480 21.20 15.00 8 12.000 6307 35 1.3780 80 3.1496 21 0.8268 26.70 19.10 8 13.494 6308 40 1.5748 90 3.5433 23 0.9055 33.50 24.00 8 15.081 6309 45 1.7717 100 3.9370 25 0.9843 40.50 32.00 8 17.462 6310 50 1.9685 110 4.3307 27 1.0630 53.00 38.50 8 19.050 6311 55 2.1654 120 4.7244 29 1.1417 62.00 45.00 8 20.638 6312 60 2.3622 130 5.1181 31 1.2205 71.50 52.00 8 22.225 6313 65 2.5591 140 5.5118 33 1.2992 82.00 60.00 8 24.000 6314 70 2.7559 150 5.9055 35 1.3780 92.50 68.00 8 25.400 6315 75 2.9528 160 6.2992 37 1.4567 104.00 77.00 8 26.988 6316 80 3.1496 170 6.6929 39 1.5354 113.00 86.50 8 28.575
