1, after a period of use and pressure, the pressure gauge movement will inevitably appear some deformation and wear, the pressure gauge will produce a variety of errors and failures. In order to ensure its original accuracy without distorting the value, it should be replaced in time to ensure that the instructions are correct, safe and reliable. 2, pressure gauges should be cleaned regularly. Because the inside of the pressure gauge is not clean, it will increase the wear of various parts, which will affect its normal work, and will seriously cause the pressure gauge to malfunction and be scrapped. 3. The pressure gauge installed in the pressure measurement site, according to the provisions of JJG52-1999, its verification period generally does not exceed six months. For pressure gauges related to production safety and environmental monitoring, the verification period must be in accordance with the verification procedures, which can only be less than six months; if the conditions for mining and mining are poor, the verification period must be shorter. 4. The pressure measurement site has large fluctuations in medium, frequent use, high accuracy requirements, and strict requirements on safety factors. The verification cycle can be appropriately shortened according to specific conditions.

Cross Roller Bearing is a special type
bearing. Because of the inner ring or outer ring were separated, after loading
the roller and the cage, it is fixed with the cross roller shaft ring to
prevent the separation, so the operation is simple when installing the cross
roller shaft ring. Since the rollers are intersected, only one set of cross
roller bearings can withstand the load in each direction, which is three to
four times more rigid than the traditional model. At the same time, because the
inner ring or outer ring of the cross Roller Bearing is a two-part structure,
the bearing clearance can be adjusted, and even if it is preloaded, it can
obtain a high-precision rotary motion. Moreover, because of its special
structure, it is commonly used in industrial robots as joint bearings.
The classification and model series of cross roller bearings are below:
RB type (outer ring segment)
RB series models for cross roller bearing, basic, inner and outer ring
size is minimal to miniaturization, its structure is the outer ring is divided,
the inner ring design is an organic whole, the inner ring spinning of high
precision parts suitable for requirements.
RE type (inner ring segment)
The RE series is a new type of XRB design concept, which is the same size
as the XRB type.The structure of the inner ring is the split type and the outer
ring is one design, which is suitable for the parts with high rotating
precision of outer ring.
RU type (inner and outer circle)
The RU series model is not required to be fixed flange and support base
due to the processing of mounting holes.In addition, due to the adoption of the
integrated inner and outer ring structure of the belt, the installation has
little effect on the performance, thus achieving stable rotation precision and
torque.Can be used for outer ring and inner ring rotation.
RBC type (outer ring segment)
The RBC series model (corresponding to the CRBC series of IKO company) is
composed of the outer ring is the split type, the inner ring is one design, and
the belt is fully loaded with roller bearings.Suitable for high rotation accuracy
of inner ring.
CRBH type (inner and outer ring)
CRBH series model, outer ring and outer ring are integral structure, used
for outer ring and inner ring rotation.
RA type (outer circle segmentation, ultrathin type)
The RA series model is the compact type that reduces the thickness of RB
and outer ring to the limit.Suitable for areas with light weight and compact
design, such as rotating parts of robot and manipulator.
SX type (outer ring segment)
The structure of SX series is similar to that of RB series. The outer ring
is a two-part structure, which is designed with three spring card rings and the
inner ring, which is suitable for the place where the inner ring has high
rotation precision.
XRU08 type (inside and outside)
XSU08 series is similar to the RU series, and the inner and outer rings
have been machined with holes, so no fixed flange and support seats are
required.Due to the adoption of the integrated inner and outer ring structure,
the installation has little effect on the performance, thus achieving stable
rotation precision and torque.Can be used for outer ring and inner ring
rotation.
