61903-2RS, Neutral, Single Row Deep Groove Ball Bearing - 61903 2rs bearing

Why Choose an Open Ended Ball Bearing?Open bearings have an open side where the balls are visible. This means they do not have a seal or shield. Open bearings are ideal for environments where they won’t come into contact with dirt as this could disrupt the bearing. Open ball bearings instead allow the lubricant inside to travel freely around the bearing for smooth running. Why Choose a Single Row Deep Groove Ball Bearing?This type of ball bearing it often the most popular because of its versatility. They are ideal for high speeds and can handle a good radial load capacity, all will very little maintenance required. “Deep Groove” refers to the race (the groove where the balls rest). There is therefore a larger space between the inner and outer rings, than the diameter of the ball. This leaves space for the rubber seals.Why choose a steel ball bearing?Steel is the perfect material for ball bearings as it provides strength and reliability whilst being corrosion-resistant. Steel ball bearings are suitable for installing as they require very little maintenance and are designed to last.

This range of ball bearings from SKF are deep groove metric ball bearings with an open end. They are extremely versatile for a wide range of applications.SKF single row, deep groove ball bearings are available with an inner diameter from 3mm to 95mm, so you will be sure to find a ball bearing for your application.

SKF Ball Bearings are designed to deliver increased reliability, reduced complexity and decreased environmental impact in high operating temperatures.Features:• Excellent performance in hot conditions, dry environments and low rotational speed applications• Temperature range -30°C to 150°C• Suitable for high and very high speeds• Steel/Ceramic ball material• Plain race type• Low friction• Available in many designs, variants and sizesWhy choose Deep Groove Ball Bearings?• For their versatility - channelling radial and axial loads they are widely used in many industries• Cost efficient - due to low friction torque the temperature remains low therefore reduces the energy cost of running in equipment such as the conveyor belt• Low maintenance - no additional lubrication after installationApplications:• Agricultural industry• Food processing• Machine Tools• Material handling • Medical/Pharmaceutical • Printing• Wind energy What is the inner ring diameter?A range between 6 mm to 40 mm What is internal/external design?• 2RS1 - Contact seal NBR on both sides 2RSH - Contact seal NBR on both sides• Z, 2Z - Shield on one or both sides• 2RSL - RSL low-friction contact seal on both sides of the bearing• 2RZ - RZ low-friction non-contact seal on both sides of the bearing• 2ZNR - Shield on both sides, snap ring groove in the outer ring, with snap ring• NR - Snap ring groove in the outer ring, with an appropriate snap ring• E - Reinforced ball set Cage Design• TN9 - Glass fibre reinforced polyamide 66 cages, rolling element centred• Stainless steel Lubrication• GJN - Grease with a polyurea thickener of consistency 2 to the NLGI scale for a temperature range -30°C to +150°C (normal fill grade) VT162 - Lubricated with Klueber Isoflex Topas NB52 grease• WT - Grease with a polyurea thickener of consistency 2 to 3 to the NLGI Scale for a temperature range –40°C to +160 °C• LHT - Grease with a lithium thickener of consistency 2 to 3 to the NLGI Scale for a temperature range –50°C to +140 °C• HT - Grease with a polyurea thickener of consistency 2 to 3 to the NLGI Scale for a temperature range –40°C to +150 °C (normal fill grade) Accuracy/Clearance• C2 - Radial internal clearance smaller than normal C3 - Internal clearance greater than normal• C4 - Radial internal clearance greater than C3• C5 - Radial internal clearance greater than C4
