What is the difference between 2RS and 2Z bearings?
Type 2 RS is a sealing type with a moulded rubber seal on both sides. Type 2 Z or ZZ is a non-removable, non-contact bearing closure with a metal seal on both sides. This type of seal doesn't make contact with the inner ring therefore, there would be no impact on the operational speed.Mar 3, 2021
What is the difference between Z and ZZ bearings?
Z designates the bearing shield, zz is a two sided shield bearing. A single sided shield bearing, "z".
What do the letters after a bearing number mean?
The letters after the bearing number indicates the presence / absence / type of shielding or sealing and any other specialties in the bearing.
What is a 608 2RS bearing?
This 608-2RS miniature ball bearing is made of chrome steel and has rubber seals. It has an 8 mm inside diameter, a 22 mm outside diameter, and a 7 mm depth. This deep groove ball bearing is used in applications such as skateboards and rollerblades, among others.
What is the difference between 2RS and RS bearings?
RS means seal on one side only and that bearing can only be lubricated from the unsealed side; 2RS would be a double sealed bearing which is factory sealed and lubricated and cannot accept any further lubrication.
What do the letters mean on a bearing?
The first digit or letter or combination of letters identifies the bearing type and eventually a basic variant. The first digit indicates the width or height series (dimensions B, T or H). The second digit identifies the diameter series (dimension D).
What is difference between ZZ and 2Z bearing?
RS - Bearing with rubber seal on one side, one side open. 2 Z / ZZ - Bearing with a metal seal on both sides. Z - Bearing with a metal seal on one side, one side open.
What does K mean in bearing?
taper bore
What is a 608 bearing?
The 608 is a 8 mm Ball Bearing that can be used in many rotary and factory automation applications. The 608 8 mm Ball Bearing Inner Dimension 8mm X Outer Dimension 22mm X Width 7mm is an open style ball bearing designed for high rotational speeds and high dynamic loads.
What does ZZ mean on bearing?
ZZ bearing means that it has metallic shield on both the sides. Generally, it contacts the outer (Stationary) and doesn't contact inner. To have a trade-off between preventing contamination ingress-ion into the bearing and frictional losses, shields or seals are used.
What is the difference between 6203 and 6203 ZZ?
The 6203 is a 17 mm Ball Bearing that can be used in many rotary and factory automation applications. The 6203 Deep Groove Ball Bearings is an open style bearing. The 6203Z ball bearing is a single row raceway and single shielded. The 6203ZZ ball bearing has a single row raceway and it is shielded on each side.
What does C mean on a bearing?
internal clearance
What is C1 c2 C3 in bearing?
These are the 5 most common C codes for internal bearing play: C1, C2, C3, C4 and C5. If a bearing has a C code, it offers extra internal clearance. C1 offers the least extra clearance, C5 offers the most extra clearance. The extra margin C3 offer is considered 'normal'.
What is the C rating on bearings?
The C value is defined as: the bearing load that will result in an ISO 281 basic rating life of 1 000 000 revolutions. It is assumed that the load is constant in magnitude and direction and is radial for radial bearings and axial, centrically acting, for thrust bearings.
What does 608 mean in bearings?
The standard inline skates bearings have the designation "608". The "608" means that the bearings are from the 600 series, with a 8mm inner diameter (the width of the hole, i.e., internal bore).May 2, 1992
What is the difference between ZZ and RS bearings?
RS provides a better seal and protection in contaminated environments but causes increased rolling friction than 2 Z as this type of seal makes contact with the inner ring. Type 2 Z or ZZ is a non-removable, non-contact bearing closure with a metal seal on both sides.Mar 3, 2021
What is the difference between 2Z and C3 bearings?
The 2Z suffix indicates that the bearing has a steel seal on both sides. The bearings are filled with a high-quality grease and are lubricated for life. The C3 in the product name means that this bearing has a higher (internal) clearance than normal. The C3 clearance is most frequently used for this type of bearings.
What does indicate C3 in bearing number?
Internal clearance being C3 means that the bearing has room for expansion if needed between the races of the bearing, whilst holding the outer ring and moving the inner ring in a radial movement you will detect a little amount of play between the two rings. C3 means the bearing has more clearance than standard.
What does 608 2RS mean?
The 608-2RS and 608-ZZ is a 8mm ball bearing that is found in many applications. The 608-2RS ball bearing has two contact rubber seals one on each side of the ball bearing. The 608-ZZ ball bearing has two non-contact metal shields one on each side of the ball bearing.
Is there a difference between bearings?
The main difference is the amount of force given to the bearings, often referred to as the 'loading weight'. As such, ball bearings handle smaller weight loads, and roller bearings handle the heavier duty loads. A ball bearing handles a thrust and radial load so that they can handle properly when in motion.

What does V stand for in bearings?
"V-shaped" marking 2). In applications where there are axial loads in both directions, the “V-shaped” marking should point in the direction of the heavier of the two loads. Section navigation. Angular contact ball bearings. Product table: Angular contact ball bearings, super-precision.
What is the difference between 608z and 608zz bearings?
608z is single shielded and 608zz is double shielded. Same bearing other than that.
