Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang TIMKEN dari 3G Electric.
What types of TIMKEN bearings does 3G Electric stock?
3G Electric stocks over 560 SKUs of TIMKEN bearings, including general purpose spherical insert bearings, rubber-mounted insert bearings, high-capacity radial ball bearings, medium duty pillow block ball bearings, and flange-mount ball bearings. Examples include the RA115RRB spherical insert bearing with a 1 15/16 in bore, the RCSM1 cartridge bearing unit with a 1 in bore, and the 6319 radial ball bearing with a 95 mm bore. These are available in both inch and metric systems.
What locking mechanisms are available on TIMKEN pillow block bearings from 3G Electric?
TIMKEN pillow block bearings supplied by 3G Electric feature either set screw or eccentric collar locking mechanisms. For example, the YASM 1-7/16 pillow block bearing uses set screws, while the RAS 1 pillow block bearing uses an eccentric collar. Both are housed in cast iron and are designed for medium duty applications.
Are TIMKEN flange-mount bearings available in metric sizes?
Yes, 3G Electric offers TIMKEN flange-mount bearings in metric sizes. For instance, the YCJ 30 SGT is a square flange mount bearing with a 30 mm bore, cast iron housing, and set screw locking. It uses NLGI 2 lithium complex grease and has a mounting bolt size of 3/8 in.
What is the maximum speed rating for TIMKEN pillow block bearings from 3G Electric?
The maximum speed rating for TIMKEN pillow block bearings varies by model. For example, the YASM 1-7/16 pillow block bearing has a maximum speed of 4700 RPM when lubricated with grease. This rating is specific to the bearing's design and lubrication, and should be verified against application conditions.
What sealing options are available on TIMKEN spherical insert bearings?
TIMKEN spherical insert bearings from 3G Electric are typically double sealed. For example, the RA115RRB and GY1015KRRB SGT both feature double seals to retain lubricant and exclude contaminants. This design reduces maintenance requirements in dusty or wet environments.
Can I find TIMKEN bearings with open designs for high-speed applications?
Yes, 3G Electric stocks TIMKEN radial ball bearings with open designs, such as the 6319 bearing (MPN 319W). This bearing has a 95 mm bore, 200 mm OD, and 45 mm width, and is open (no seals or shields), making it suitable for applications requiring higher speeds or custom lubrication systems.
